SOLIDWORKS Simulation Yield Template

If you are tired of repeatedly changing settings for every new Simulation study you create, you may want to consider going to your Default Options (see below) and making a few customizations. With a few exceptions, these options are only applied to any NEW study that you create, so these options behave like a template for your Simulations. I’ve listed out some of my favorite customizations, but you might tweak these to better suit your needs.

Simulation Default Options

1.) Change Units for Displacement, Stress & Temperature

  • If I feel like working in SI, I usually change these:

    Meter to Millimeter No brainer. Maybe you even want to use microns.
    Kelvin to Celsius I usually end up converting to Celsius in my head anyway.
    Steel Yield Strengths Many steel yield strengths are roughly between 100-1000 N/mm^2

  • Or, for English, these options give me numbers that are short and sweet:

    Inches to mil One mil equals one thousandth of an inch. Nice and simple.
    PSI to KSI Many steel yield strengths are roughly between 20-200 ksi

2.) Switch the mesh to Curvature Based

I believe that the Curvature based mesher is usually more robust that the Standard mesher.

3.) Save Result Files Under a Results Folder

  • If you are working on your files LOCALLY, using a sub folder keeps your folders clean:

    SOLIDWORKS Document Folder - Results

  • Or, if your files are on a NETWORK, you can force the study to save the results locally for better performance and stability:

    User Defined Document Folder for Results

4.) Show Maximum Values on Plots

Show maximum values on plot

Adjusting this option will create these maximum notes by default:

5.) Change "Number Format" to General

Say goodbye to scientific notation, but not entirely. The nice thing about “General” is that it will display scientific notation only if the numbers are really large or really small.

6.) Set Upper FOS Limit to Ten

Some regions in your model might have stresses near zero. This means that FOS will be near infinity. This makes your color charts for FOS difficult to interpret. Setting this option should make this easier.

7.) Customize Default Plots

The three default plots you see under Static Study Results are are created automatically after you run the study. Plot3 is set to strain. Since I don’t look at strains frequently, I usually change this one to FOS or simply delete it. You can add more default plots to this list, if you prefer.
