More Than One Way to Perform Thermal Stress Analysis in SolidWorks Simuation

While the goals of analysis are the same, the assumptions made determine the method and final results.

14-Nov-Hawk-Ridge-Systems-Simulation-360Did you know that there are up to 15 ways to setup and run a thermal stress analysis using the tools in SOLIDWORKS Simulation and SOLIDWORKS Flow Simulation? While the goals for a thermal stress analysis are the same, the assumptions you make and what you want to consider in your analysis all play a role in choosing a method and the final results you obtain.

Below is a handy table that outlines some of the assumptions and considerations you can make for a particular method along with what minimum Simulation software package is needed. You can also download this chart as a PDF.
