How do you perform a GROUNDCHECK with G, F, A, and N DOF sets selected ?

Guillaume Leclere

Hi,

 

I am encountering a problem trying to run a GROUNDCHECK inside of HyperMesh 2023.1, because I cannot find the subcase information entry as specified in the documentation. Here is a photo of the documentation :

The only GROUNDCHECK I have been able to find is the GROUNDCHECK CARD, however, it does not let me select the DOF sets that I want, and instead doesn't offer the option to choose at all, and selects the G-set after consultation of the output file for the analysis.

Is it even possible for me to choose the DOF sets I want for my modal analysis?

I use HyperMesh 2023.1 with a student license.

 

Thank you for your help,

Guillaume LECLERE

Hello Guillaume,

For reference, you will need to modify the GROUNDCHECK command in the input deck for OptiStruct as there is not a field to add this in HyperMesh v2023.1.  The command to do this is below or similar:

GROUNDCHECK (PRINT,SET=ALL) = YES

This should print out rigid body checks with G, N, F, and A-sets as in attached model.

Thanks,

Rob H.
