*** ERROR 14: Missing property # 1 referenced by CQUAD4 # 13.

JC_22453

Hello,

I am relatively new and am beginning to learn how to use HyperWorks.

I was playing around and I created this wing model of an A320 in Solidworks which I imported into hyperworks as an .isg file and created a rigid body mesh from it. I was also playing around with the pressure loads as you can see from the file which I attached.

When I run the analysis (linear static) I come across this error:

I saw in the community that we had to assign properties to these CQUAD4s but looking at them, they ll seem to have a property assigned already.

So I do not know what I am doing wrong here. Can anyone help me?

Hey JC,

That's happening because CQUAD4 elements need a PSHELL property. Also, RBE2 (Rigid) elements should be in a separate component, since they don't need properties.
