GPFORCE/SPCForce

Altair Forum User

I request for the reaction force output to see it in the HV/HG result types menu. In Optistruct, I activate GPFORCE from GLOBAL_OUTPUT_REQUEST & also in loadstep activate Analysis,Output as a displacement,stress and GPFORCE option.Finally I ran the NLGEOM analysis and trying to see the results in hyperview,but  i am unable to see the GPFORCE in result types menu.Please suggest the solution.

As per you suggested i use the OP2 format for NLGeom static analysis, i am able to see only the stress and displacement plot but unable to find exact force through GPFORCE command. Please suggest the solution in proper step.

Please sir suggest the solution.

Tushar,

 

GPFORCE is not supported for NLGEOM,

 

Instead you can run NLSTAT.

hi Prakash,

 

could you tell me an option for Geom non-linear analysis where i should get a GPFORCE-Displacement diagram? with Nonlinear quasi static i can not solve because of contact.

 

Thanks in advance!

You can run the NLGEOM analysis which will write out .rad files. Use these files in RADIOSS to request reaction forces using output blocks.
