Multiple Flow Result Plots in E-Drawings for 2014

Tuesday, April 22nd, 2014

New for 2014, The ability to save multiple result plots in one E-Drawings file.  Previously the result plots needed to be saved in individual E-Drawings files. This caused more files to be generated and shared than need be.

To generate multiple result file plots in one E-Drawings file follow this procedure.

  • Show all plots desired to be included in the E-Drawings file
  • Right Mouse Button on the Results Folder and Select Save Image
EDrawings Save Image

E-Drawings Save Image

  • Choose the E-Drawings File Format
EDrawings Pull Down

E-Drawings Pull Down

Once in E-Drawings you can turn on or off the individual plots as needed to convey the content you wish to show.

Weldments and Bill of Materials

Wednesday, March 26th, 2014

There are many different ways to create structural frames.  One method might be creating it as an assembly with many individual parts.  Another method, which is my preferred  way, would be as a single multibody part…as a Weldment.
Weldment Icon
The Weldment way allows for easy design changes, automatic structural member trimming/extensions, and creation of cut lengths.  This however is typically just a portion of the overall design.  There might be many more pieces that go on the frame.  This is when you would add your Weldment design to an assembly.

Now with your Weldment in the assembly and the other components attached, you need a Bill of Materials (BOM).  It’s possibly to show the cut list for all the structural members in an assembly BOM.  You will need to choose a BOM Type of Indented in the PropertyManager.

BOM Property Manager
Once you choose the indented type, the BOM will show as a cut list.  The QTY column shows a total length for the structural member.

If you then choose “Detailed cut list” in the BOM Type, it will break each member out in their own row with a length value.

Now your assembly BOMs can show all the individual items even in the Weldment.  But what if you are using Enterprise PDM.  Can you see the cut list in EPDM?  Of course you can.  It is under the Bill of Materials tab.  You would need to set-up a Weldment Cut List template in EPDM but that is very simple.

EPDM Cut List
As you can see, the cut list item names can be shown to make finding the correct member easy.  Just like in a drawing, you can choose to see a Weldment BOM.

EPDM Weldment BOM
This will group all the members together giving you a total quantity.  If you select the “Contains” tab, and RMB on a Weldment member, you get some more useful functionality.

EPDM Contains Tab
When you choose “Properties”, you can see the members data card with the length.

You will need to add the length field to the card and map it to the “BOM Quantity” variable.

Flow Simulation ‘Replicate Condition’

Thursday, March 20th, 2014

New for 2014 a user has the ability to apply a single Boundary Condition to multiple instances of the same part.  This is a great time saving tip.  No more manually adding the same Boundary Condition to instances of the a part.

With your setup you can assign Boundary Conditions such as an “Inlet”, “Outlet”, and “Heat Source” to  “Part1 “(face/volume) for example.

Simply Right Mouse Button the Boundary Condition and select “Copy to Component Instance”.

The Boundary Condition auto populates on all “Part 1s” in the model.

You can deselect the instance(s) you do not want included.

Note: the “Part 1″ needs to be a part in an assembly for the transfer to work.

For the full pdf instructions please see the link below:

Circuit Works and Flow Simulation Working Together

Tuesday, February 25th, 2014

When you think about it, it makes sense that different parts of our SolidWorks Software work together to make a total package.  Keeping in this tradition now in 2014 Circuit Works and Flow Simulation work together to make your life easier.

2014 Flow simulation now imports the Circuit Works component properties and applies them automatically as boundary conditions in your Flow Simulation setup.  Previously these properties would be input manually.  Now we can import ECAD file PCB or Component Thermal Properties to Flow Simulation.

Circuit Board

Circuit Board

Some of the properties that can be directly utilized from Circuit Works are, Dielectric and Conductor Density, Specific Heat, Conductivity for PCBs, and Conductivity for Volumetric Heat Sources.

Circuit Board Thermal Flow

Two Import Options:

Right-click Heat Sources and select Import volume source from model. Select the heat sources to import in Item properties.
Right-click Printed Circuit Boards and select Import Printed Circuit Boards from model. Select the PCBs to import in Item properties.

Import Interface

If you are doing Flow Simulation on Electronics Enclosures check out the new Circuit Works import options.  This new feature is a great time saver.  Manually adding these properties on a typical circuit board (100′s of components) is tedious and time consuming.  Circuit Works integration brings this task down to a few simple clicks.

What Can’t You Design In SolidWorks? #3

RC Hovercraft #3 – SolidWorks Simulation

To review, I had 4 main design criteria for the Remote Control Hover Craft.

  • Utilize the SolidWorks and SolidWorks Simulation Suite of software to develop and optimize the hovercraft design.
  • The RC Hovercraft’s main components will be 3D Printed using the Stratasys UPrint.
  • Easy to Assemble. I want to make the assembly as easy and as straight forward as possible with concise instructions.
  • For purchased components, use low cost, off the shelf components including the electric motors, electronic speed control (ESC), batteries, and propellers.

The next step of the design process is to verify using  SolidWorks Flow Simulation  that the motor and propeller combination will provide a proper amount of air flow to lift the hover craft.

Flow Simulation provides an understanding of  flow in an internal or external volume.  Flow Simulation calculates flow with media including Gases, Fluids, Real Gases, and Non Newtonian Fluids.  Flow Rate, Velocity, Pressure , Vortices, and many other parameters are calculated during the solution.

The following  calculation with the provided manufacturer information was used to calculate the flow parameter boundary conditions for the simulation.

CFM = Cubic Feet per Minute = Volumetric Flow Rate

Mass Flow Rate = (Density) x (Volumetric Flow Rate)

Newton’s Second Law of Motion:  Force = (Mass) x (Acceleration), or F = ma

F = ma = (Mass Flow Rate) x (Velocity), given a constant flow velocity

(i.e., constant propeller speed and pitch angle).

Velocity = (Volumetric Flow Rate) / (Area), where Area = (Pi) x (r^2), the

length of a propeller blade is a good approximation for the radius, r.

Thrust = (Density) x (CFM^2) / ((Pi) x (r^2))

Note: Keep track of your units!

The hover craft’s Flow Simulation was approached from an external analysis type.  A volume was specified around the  hover craft to capture flow into the  inlet and out of the bladder, and its effect from the surrounding environment.  A fan was used to provide the draw of air through the inlet into the internals of the hover craft.  Parts of the hover craft were removed including the canopy cover batteries, and escs.  These components are unnecessary for teh flow run and would increase computational time.

 

Air Velocity

The results from the Flow Simulation run show a symmetric and even outlet pattern of flow from the Hover Craft’s “Bladder”.  The parameters provided by the flow simulation suggest that the motor and propeller combination should be sufficient for lifting the craft.

How to Design a Garage in SolidWorks

Saturday, January 18th, 2014

If you’re into home improvements like I am, it’s that time of the year to start designing your summer projects.  It’s going to be another eventful year at the Tadic household as I plan to have my dream garage/studio built.  This is all possible due to a local vocational school that has offered to build it for only $500 (I will have to pay for all materials).  Normally, I’d be pretty skeptical about a service like this, but fortunately I was able to witness them do an amazing job on a garage a few blocks away.

So, if you’re game to take on a garage construction project this summer, get a kick start on the design with my SolidWorks model that I uploaded to GrabCAD.

garage

If a garage is a bit too much for your summer’s agenda, maybe you could focus on replacing those rickety steps on your porch instead.  This SolidWorks model is equipped with a complete list of comments that can be reviewed with Part Reviewer.  The stairs are fully configurable to any size you may need.  All you have to do is punch in your overall dimensions.

SolidWorks 2014 Sketch Auto Scale

Tuesday, January 7th, 2014

One of my favorite enhancements in SolidWorks 2014 is the sketch auto scale.  It’s on of my top 10 enhancement because it saves so much time and frustration.  Here’s how it helps you.

When you create a sketch, you most likely don’t add dimensions right away.  You will get the rough shape on the screen and then come back and add the dimensions.  In 2013 and pervious, once you would add these dimensions, the sketch would possibly move all over the screen.  That’s because if you sketched a line that was 10mm but then placed a dimension that made the line 100mm the zoom wouldn’t change.

Well now in 2014, when you add the first dimension, the entire sketch will scale to that value.  So if you tell the 10mm line to be 100mm, it looks like nothing has changed and you originally sketched the line at 100mm.  It’s all based off the very first dimension you place in the sketch.

If you want to watch a video of this and some other new enhancements, check out our What’s New video.  It can be found here: http://www.3dvision.com/whats-new-in-solidworks-2014?view=form

Mesh Improvements For Simulation Flow

Monday, December 2nd, 2013

SolidWorks Flow 2014 has been released and there are several updates.  I want to talk about the Mesh Improvements inside of Flow Simulation.

Two Main Changes:

  • Mesh Parallelization
  • Local Initial Mesh Regions now Adaptive

 

Lets discuss the Mesh Parallelization first.  There are three stages during mesh generation in Flow Simulation  Geometry Evaluation, Mesh Capture, and Mesh Saving.

Flow Simulation in 2013 utilized one processor for all three mesh operations.  Flow Simulation 2014 utilizes multiple cores(user specified) for the Mesh Capture(resource intense) portion of the process.  This speeds up the mesh drastically between versions.  A 1.5 million cell model in 2013 took 23 minutes to mesh.  In 2014 the same computer, model, and mesh settings took 11 minutes. Over a 50% improvement for this example model.

 

Adaptive Meshing has always been available in Flow Simulation, however it was only effective on the entire computational domain.  Adaptive meshing is a setting that allows the software to automatically refine areas of high gradient in the flow, allowing the software to converge the results.  Adaptive meshing on a localized region is now available for 2014.  A localized region is a region that a user specifies to have manual mesh refinements on.  This is done by inserting a body in the flow region and specifying it as a local initial mesh.  This region can now be specified to be affected by adaptive meshing.  This speeds up convergence by localizing the adaptive changes.

How Much Does it Cost?

Wednesday, November 13th, 2013

When you create a new design, you need to know how much it costs.  Are you going to be over budget or under?  How do you find the cost of your sheet metal or machined parts?  I would guess that you have an elaborate spreadsheet that you use to “guess” the price or you just compare it to a similar design.  Well if you have SolidWorks Professional or Premium, you could use SolidWorks Costing.

Costing Icon

SolidWorks Costing is a cost estimation tool that uses 3D geometry to estimate the final cost.  It doesn’t matter how the part was created in SolidWorks, it’s all about the geometry.  SolidWorks Costing will detect cuts, holes, bends, slots, etc.  It then applies a cost to each of these giving you a total cost.

Costing Folders

Where do you find this tool?  It’s under Tools>Costing.  There is just one button for Sheet Metal and Machining.  It will add another tab to the FeatureManager Design Tree.

Costing Folders Multibody

It will also add another tab to the Task Pane.  The Task Pane is where you fill in information about the costing such as number of parts to be made, material type, blank size, etc.

Costing

Where does it get the prices?  SolidWorks Costing uses templates that you can customize.  You add in the price of the material, the machines that you have, etc.  There will be a Sheet Metal template and a Machining template.  The Sheet Metal template would be for all Sheet Metal parts.  The Machining template would be used for all milled and turned parts.

Machining

Once you have the cost analysis done, you can create a report.  This can be exported as a Word or Excel document.  SolidWorks also allows you to add specific cost properties to the Part Properties.  These can be pushed to a BOM, to the drawing, or to Enterprise PDM.

Costing Properties

 

Now you will be able to discover how much your designs cost.  Give it a try.  If you have questions, check the help file or give your VAR a call.
