Error Running an FEA
Altair EmployeeHi,
I am trying to run an FEA on a truss section. The setup is that it is supported on both sides, with a 937.5 psi load distributed over a 4' by 4' square. After I went through the setup following a tutorial, I tried running it and it gave me the following error. As of now I put a dconstrain on the magdisp, but I'm not sure if that was right. I'd appreciate any help. I have attached the file below.
Messages for the job:
*** ERROR # 1908 ***
Case Control data LOAD=2 is not referenced by any bulk data
relevant for used subcase type.
*** Run terminated because of error(s) in the input data.
Thanks!

HI @nlahiri
Pressure is organized in a wrong load collector and PSHELL card has no thickness.
I have given a thickness of 1 to check and works but results are not meaningful.
Provide the right thickness and run again.

Is the shell necessary? Can I run an FEA with just a solid? On the video I watched it said to create both. I will try rerunning it at a lower thickness.

Hi,
Can you share the video link, please?

Thanks for the help. I watched this series:

I changed the thickness again as they did in the video, but it didn't run.

Hi,
Not sure about the tutorial and shell elements. But I see that the solid elements are tetras and shells are quads.
This makes no connectivity between shell and solid component.
Also, I see a pressure of 6.5e6 on each node. Which I think is huge. Please check that as well.

I made the solid and shell both triangles. Would it be possible to do this without the shell?

Yes, Shells may have used to extract surface stresses.
But analysis should run without shells.

I think I am missing something, because it still doesn't work even though I removed the shell and changed the pressure.

Can you check the units of the load and also the model?

Hi,
Thanks for all the help. I forgot to reply to this, but I think I was mainly having problems setting it up right.
Thanks,
