Lesson goal
Identify the situations where a static study is not enough, and set up the right study: frequency, fatigue, thermal or load combinations.

1. Watch the videos
Dassault Systèmes videos hosted on MySolidWorks: they open in a new tab and a free account is enough. Watch them in order.
Frequency Analysis of an AssemblyCalculate the natural modes and spot resonance risks.↗ Fatigue AnalysisLife under repeated loads with S-N curves.↗ Thermal Analysis with RadiationConduction, convection and radiation in a thermal study.↗ The Load Case ManagerCombine several loads and compare the cases in a single study.↗
2. Key takeaways
A part vibrating near its natural frequency can fail under a modest load: compare the modes with the excitation frequencies (motor, rotation).
Fatigue applies to repeated loads: a part that holds in static analysis can fail after thousands of cycles.
A thermal study gives the temperatures, which you can feed into a static study for thermal expansion.
The Load Case Manager saves you from duplicating studies for each load combination.
Tip
These studies depend on your license (SOLIDWORKS Simulation Standard, Professional or Premium). Check with your Ohmycad engineer before you start.
