Snapshot of velocity in X direction showing wave interaction with hole

Model Description

Simple 2D model with an unstructured mesh of a wave propagating in steel containing a hole. The model is set up using the CAD command and the wave is generated from a pressure load applied to the edge of the model.

Basic Model Schematic

Mesh

The triangle element type was used to capture the hole detail. The number of elements was set using the number of samples option in the cad mopt_tri command. 200 sampling points was sufficient to represent the hole.
