Simulation 2009 What’s New (Part II)

Friday, October 10th, 2008

Hey everyone.  Back for the second installment of What’s New in Simulation 2009.  Let’s jump right in.

Material

In the past, COSMOS and SolidWorks utilized separate material databases.  The SolidWorks material could be used in a COSMOS study but the databases were separate.  In general, the SolidWorks materials did not contain as many properties as the COSMOS materials.  This is no longer the case in 2009.  There is now a combined database for SolidWorks and Simulation.  The materials dialogue box has been enhanced as well.  Three new tabs have been added:

     -   The Custom Properties tab has been added to add properties for custom defined materials. 

     -  The Application Data tab allows the user to add information / details pertaining to custom defined materials. 

A Favorites tab has been added to make it quick in easy to select your most used materials.  A Source field has been added so the source of properties, tables and curves, and Fatigue SN curves can be documented within the material definition.  A default failure criterion can be selected for each material.  If you utilize the automatic setting in a FOS plot setup, the default criterion specified for the material will be used.

Thermal Studies

There are two changes for thermal studies that I am absolutely thrilled about.  There is now a button to “Select all exposed faces” when applying thermal loads.  That’s right.  No more rotating the model to select every single face of a model to apply a temperature!   Something so simple that brings so much joy…

The other big change is that you are no longer required to copy the same mesh from a thermal study when applying thermal results to another study.  This is a huge improvement.  It is no longer necessary to apply a thermal resistance contact condition everywhere a no penetration or bonded contact condition needs to be in the static or non-linear study.  Those of you who deal with this on a regular basis are granted a cone of silence so you can jump for joy and scream at the top of your lungs. 

Revolutionaries Unite…

That’s right folks!  The riots and marches on headquarters have finally brought them to their knees!  They couldn’t hold us down forever!!!  There is now a simple way to save out a deformed shape from a Simulation analysis! 

It took them long enough to do this but they did it right.  To save out a deformed shape, right click on the Results folder and select “Create Body from Deformed Shape…”.  You can either save it out as a configuration or a new part.  Type in a name, click the green check mark and boom!  You have a model that is the deformed shape of your analysis.  This is of course imported geometry so the design tree for the deformed part contains only “Imported1”. 

Power to the people!  Now what am I going to do with all these extra berets

Part III coming soon!  Stay tuned…

What’s New in SolidWorks 2009 in Louisville…I think

Thursday, October 9th, 2008

You know that joke where the singer in a band has the city he is in written on the back of his guitar so he doesn’t accidentally yell out: “Springfield ROCKS” when he is actually in Akron? At least I always thought it was a joke, but here we are –half way through our “What’s New” tour and I only have a faint idea where I am and where I am going.

During my presentation today I had a thought. [I've done the "What's New in SolidWorks Enterprise 2009" presentation so many times, I can now think of other things as I am talking.]

In SolidWorks Enterprise 2009, they introduced a way that you can see the BOM tables in your drawing and assembly files within the Enterprise interface. The good thing with this ability is that you can see the BOM in your file without having to open it. Additionally, if you spend a lot of time making your BOMs the way you want them in your drawings (and assemblies) you should be able to take advantage of this work in Enterprise.

The more I think of this feature the less I like it.

First, our goal should be to not use these BOMs in the files in the first place. Why “spend time” goofing with these BOM tables in your files when you get a calculated BOM from Enterprise with no effort at all?

Okay, okay, I hear you arguing that you need to have the BOMs on the drawings for the poor guy assembling this file who apparently doesn’t have any electricity and thus has no access to Enterprise. Fine, fine, keep your old 1870′s technology, but let me give you a warning: The new BOM tables as shown in Enterprise can be wrong! Consider this scenario:

  1. Check in a drawing of an assembly that contains a BOM table, but leave the assembly checked out
  2.  Modify the assembly in a way that the BOM would change.

Now, if you open the drawing in SolidWorks, the BOM would be correct – because the BOM table rebuilds as soon as it loads. However the BOM table in Enterprise is still what the BOM table looked like when the drawing was checked in. [Also be aware if you open this drawing in eDrawings, the BOM table is dirty as well.]

Sure there are work-a-rounds -or this problem could be alleviated with user training, but IMHO, the risk to benefit ratio of this new ability is pretty high.

At today’s “What’s New” in Louisville, Vik Vedantham was wearing charcoal gray slacks with his blue 3DVision shirt. For those of you have been asking…I have no idea if that is his real hair.

No groupies at today’s event.

Off to Bowling Green, Kentucky.

SolidWorks in the Commonwealth

Wednesday, October 8th, 2008

Today the “What’s New in SolidWorks 2009″ party arrived in Lexington.

Yesterday I asked a customer if I would see him today at this rollout. He stated that his company is still using SolidWorks 2007 and his IS department has no short term plans to upgrade to 2009.

[My first reaction was anger. I hate it when IS departments determine what is best for other departments. Their job is supposed to support the company, but so often the tail wags the dog. <sigh> this is a blog for another day] I counted to ten. I admit I do see this customer’s point. However I contend it is still important to come see what is new in the software so you can plan; and look for a valuable new feature that would make the return on investment worth going to the CEO and tattling on the IS guys for not doing their job.

One other [perhaps more professional] reason: Any time you can watch a guy who is really good with SolidWorks (as an example Randy Simmons; who did the rollout today) you need to take some time to watch. There are so many things in SolidWorks, you always pick up something new. Here is an example: Randy was showing the new 2009 ability to put custom properties into equations. His example was he was taking the part’s mass and multiplying it by a constant “$/pound”. Thus the cost of the part updates automatically through equations. Several people in the room did not know that SolidWorks could automatically tell you what the weight of a part is….and has been able to do this since the beginning. They had been doing this by hand! You may have already known this, but think of the time these guys saved just with a little aside like that. I know that everyone in the room picked up a little tip today – something to make them a better SolidWorks user than their competition.

Vik Vedantham was wearing gray slacks with his “peach” 3DVision shirt –overall a great ensemble.

It is now Wednesday and still no groupies. Is it possible they don’t follow engineering functions?

Off to Louisville Kentucky.

The What’s New carravan arrives in Cleveland

Tuesday, October 7th, 2008

This blog entry brought to you today commercial free by InspectionXpert. When you need to create inspection sheets, and they need to be done right, trust InspectionXpert. Ask your friendly neighborhood 3DVision sales representative today!

So today for the third stop on the tour, we are in Solon.

For those of you who like to put a face with the name, Robert Warren, our three time Top Gun support guy, made a guest appearance.

Robert and Jordan eating lunch That is Robert on the left, Jordan Tadic on the right. Suppose Robert’s Grandfather is walking around mumbling -trying to figure out where his favorite tie went?

Vik Vedantham was wearing gray slacks with his orange 3DVision shirt. He mixed things up a bit by wearing black shoes instead of the brown ones he wore Friday –overall a great ensemble.

I thought I saw our first groupies…but turns out it was just the line waiting to get into the women’s locker room.

Off to Lexington Kentucky.

SolidWorks in Toledo

Monday, October 6th, 2008

Toledo. Home of Tony Packos, the Mud Hens, Jamie Farr, and the second stop on 3DVision’s What’s New in SolidWorks 2009 tour.

I have been looking forward to this day for a while. This is the first time I have gotten to see our new applications engineer, Jordan Tadic in action. It appears he is as good as advertised. He had good pace and really was able to show the cool new features well. The people of Northern Ohio have it pretty good.

It always interests me how different groups have personalities. I had very few questions in Cincy, but almost 15 minutes worth of questions here in Toledo….from many people too, not just one guy hogging up all the time. Several people were very interested in Enterprise’s new ability to confirm state changes with password verification.

As a change of pace, Balaji Chandrasekaran from SolidWorks showed the new features of Cosmos. Check out Seth’s post that he did earlier today.

There were no groupies; perhaps the word out on the street isn’t out yet?

See ya in Cleveland.

COSMOS 2009 What’s New

Monday, October 6th, 2008

Hey everyone.  I am going to be outlining some of the key changes to the simulation tools within SolidWorks 2009 over the next couple blog entries.  This is in no way meant to be a complete list of all the enhancements / changes within 2009 but a discussion of the highlights as well as some necessary information meant to make your transition to ’09 as productive and seamless as possible.  A complete description of changes can be found in the What’s New document which can be found under the Help menu in SolidWorks 2009.  These blog entries will loosely follow the outline of the chapter 10 of this document if you want to refer to it for further clarification.

SolidWorks Simulation?!!!

Let’s jump into the changes.  That’s right folks.    It starts right at the top with a name change.  No more COSMOS.  The name has been changed to SolidWorks Simulation.  Here is a rundown of all the product name changes:

COSMOSWorks                                          →                 SolidWorks Simulation

COSMOSWorks Professional                  →        SolidWorks Simulation Professional

COSMOSWorks Advanced Professional  →             SolidWorks Simulation Premium

COSMOSXpress                                         →                 SolidWorks SimulationXpress

COSMOSFloXpress                                    →                 SolidWorks FloXpress

COSMOSFloWorks                                    →                  SolidWorks Flow Simulation

COSMOSMotion                                        →                  SolidWorks Motion

Keep this in mind because from now on the new naming convention will be utilized in the remainder of this and all subsequent blogs.

“Where’s my COSMOS tab?” – User Interface Changes

I’m sure I will be getting a lot of this one.  SolidWorks Simulation features a significant user interface change.  You will no longer have a COSMOS tab in your feature manager tree.  You will now have a Solidworks Simulation tab at the bottom of you design window, in the same neighborhood that the Motion tab moved in 2008.  You will have a new tab for each Simulation study.  When a Simulation tab is selected, a Simulation tree overlaps the SolidWorks feature manager tree.  You will only be able to see one Simulation setup at a time since they are on different tabs but items can still be drag and dropped to other studies.  To do this, select the items to transfer, and drag and drop them onto the desired Simulation tab.  Studies can now be renamed or duplicated by right clicking on the corresponding tab and selecting either rename or duplicate.

Within the Simulation tree, there has also been changes.  The Loads / Restraints folder is no more.  Restraints are now located under Fixtures.  Loads are located under External Loads and thermal loads are listed under Thermal Loads.  Connector and contact conditions are under Connections.

Here’s one that I am extremely excited about.  It is now possible to add split lines within Simulation.  It is no longer required to switch back to the SolidWorks tab to add your split lines.  A Split tab has been added to the property managers for Fixtures, External Loads, and Connectors.  The user can click on this tab within the property manager, create a sketch of the required split area, apply it to the required faces, and then apply the appropriate loads / restraints etc. within the same property manager.  This one can be a big time saver.

When applying a load / restraint / connector, the symbol will appear on the model as a preview to give you a better idea of what you are doing.  It is now possible to double click a symbol in the design window and bring up the corresponding Property Manager.

These interface changes are significant and will take some time to get used to.  In an attempt to ease the adaptation process, a set of four videos will pop up when Simulation is first added in.  These videos will pop up for viewing everytime Simulation is added in until the user selects a button to turn them off.  I highly recommend viewing them each a couple times to get a grasp of the changes in the interface and the work flow.

Cincinnati or bust

Friday, October 3rd, 2008

What do Skip Prosser, Thad Matta and Scott High have in common? They all totally dominated in Xavier’s Cintas Center!

Xavier Basketball Court
Today, in Cincinnati, was 3DVision’s first stop on our whirlwind tour showing off the new features of SolidWorks 2009. The room we were in was only yards away from the Musketeer’s home court. It was pretty cool.

It was great fun watching people’s reaction when they saw the new features for the first time. I like to think the new BOM features found in Enterprise stole the show, but the crowd seemed to be the most interested in the PhotoView 360 package.

Scott High in action

(The pic above is of Scott in action. With those two bright projector screens my cheap camera phone didn’t have a chance!)

Vik Vedantham was wearing gray slacks and an oversized gray sweatshirt with his orange 3DVision shirt underneath. I don’t know who his barber is, I hope Vik tipped him well, he did a great job –overall a great ensemble.

There were no groupies; but this is our first stop. I am hopeful they will start showing at our other events.

See ya in Toledo.
