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.
- Model Description
- The following files are needed for this tutorial:
- Random.ssp
- PSD_Function.csv
Open Project
- Start a new SimSolid session.
- On the main window toolbar, click Open Project .
- In the Open project file dialog, choose Random.ssp
- Click OK.

Edit Solution Settings
- In the Analysis branch of the Project Tree, double-click on Solution settings.
- In the Solution settings dialog, for Adaptation select Global+Local in the drop-down menu.
- Click OK.
Run Analysis
- On the Project Tree, open the Analysis Workbench.
