FBD in 1D beams
Hi everyone,
i want to solve this problem where there are forces on the 4 point and check the FBD forces at the constraints. i run it in the solver optistruct and got the result. When i open the fem and op2 file in hyperview to check the FBD then it opens the file but when i select an element or node an error message showing 'no valid cross-section for plotting' and doesn't work.

Just to make sure, have you looked at the documentation for FBD in HV?
Also there's a post at Altair University showing how to use it. It might help you, maybe.

Thanks Adriano. I have already seen the video.
How can i make sure that my exported .fem and .op2 file has the values of GPFORCE. Its seems like that is the main problem. the solver is not generating the values GPFORCE in .op2 and .fem files.
Also while generating .h3d there are 'no values for grid point element forces' and 'no gird point element moment'0 -
You should request GPFORCE Output in OP2 format.
In HM you can add GLOBAL OUTPUT REQUEST and then, check GPFORCE, and under FORMAT choose OP2.
Make sure this is created in your model.

I running force transmissibility therfore I requested this option but I obtained this error
'No output results requested for Frequency Response, Transient Analysis
or Random Response.'no

Thanks Everyone. It worked. The output was there but iwas not selecting the Elements in the FBD plot correctly but the video helped. I output the Files in .fem and .op2 and used them in Hyperview along with advanced format
