Create coincident Nodes and Meshes at contact surfaces

Recommended Posts

Hello,

 

there are several ways to put two or more parts into contact in HyperWorks for the OptiStruct (and other) FEM solvers:

1) To have a defined identical and connected mesh node pattern on both contacting surfaces

2) To have a defined "FREEZE" Contact definition between non-identical mesh patterns

 

The first way - identical mesh patterns -  is described in the first flash video attached to this post.

There is a second video that describes the creation of identical meshes in case of unconnected contact surfaces (gap between the two CAD parts)

The third video describes the automatic seupt of FREEZE contact between multiple parts.

I also attached the HM 2017 models to reproduce the videos.

 

Best Regards

 Jan
