Optistruct Error '76

Felix_21658

Dear community,

I am working on an exercise for university and this is my first time constructing and analyzing in Hyperworks. Unfortunately, I get an error when I want to analyze my construct. The error code tells me this:

 *** ERROR #  78 ***
 PLSOLID data can only reference MATHE data.
 This error is for MID #        1,
 referenced by PLSOLID #        1.

I would really appreciate it if you are able to get me on the right track. I am really unsure how I can solve this issue.
I also added the FM file and the exercise as an attachment.

Best regards and thank you very much in advance,

Felix

Hello Felix,

Use PSOLID instead of PLSOLID which is used for hyperelastic material (MATHE).

You also need either to delete the PSHELL elements or to assign a PSHELL property to them.

Use VALIDATE>FREE EDGES>equivalent nodes to fix the free nodes.

Finally, define a subcase and apply any load (you can use a rbe2 element in the hole to apply it).

PS: I'm attaching a model just as an example, adjust it at your convenience.

The model has first-order and second-order elements at the same component. Be sure you are using elements well-connected (you could use only first-order elements, for example).

The mesh is unconnected as shown in the picture, you should fix it as well.

Thank you,
