HyperView results - Surface average contact pressure from results

There was an error rendering this rich post.

Hello everybody,

I open this discussion in order to have more information about the HyperView results analysis. In detail I performed a contact analysis with OptiStruct (through SIMLAB) and I would like to calculate the average Pressure (or other quantity) for a surface of the body.

First of all I cannot understand if I need to create a set of nodes/face and how to calculate the average values.

thanks

Hello,

For Optistruct, if you request CONTF(OPTI) output, the total contact force, normal contact force, tangential contact force, and contact area results are output to the .cntf file.

The .cntf file can be read directly in HyperGraph.

Hello,

In case I cannot run again the simulation how can I calculate?

Thanks
