Optistruct - Force simulation
Altair EmployeeDear All,
I am using Altair HyperWorks software to check and control the results of some new method, for structure borne noise characterisation, which I am investigating.
I am normally operating with mobilities (velocities) in particular nodes, while doing frequency response analysis (modal), but now I would need to simulate / measure forces in the nodes where spring attaches to my structures. (picture enclosed).
I have tried many different ways of gaining correct force information, but I was always unsuccessful.
I used GPFORCE output at freq. response analysis and than tried to plot total force, force in element, MPCForce, Applied force and everything else I found, but non of those options gave me the right result.
Could you give me some advice, how to “simulate” / “measure” the force on both sides of spring?
Because if spring is not massless force on one side will be different as force on the other side and I want to see the difference for various cases of my experiment.
Thank you very much for your help!
Best regards,
Luka Trampus

File format you have requested to output GPFORCE is h3d or Op2?
Tell us the which version of Hyperworks you are using at your end?

File format is h3d and I am using HyperWorks 13.0.
Thank you!

Please output results in op2 format & if have access to latest version 14.0 try it.

GPFORCE in .h3d output is specifically added for the load transfer path analysis with NVDirector. It is only available for linear static, frequency response, and acoustic analyses.
