# SS-T: 4070 Random Response Analysis

Create random response analysis in SimSolid.

- Purpose
- SimSolid performs meshless structural
analysis that works on full featured parts and assemblies, is tolerant of
geometric imperfections, and runs in seconds to minutes. In this tutorial,
you will do the following:
- Create dynamic random analysis for a walkway assembly with base excitation load.
