*** ERROR 14: Missing property # 2 referenced by CQUAD4 # 1.
Altair EmployeeHello everyone,
I'm pretty new to HyperWorks and have been struggling for a couple of days with this error when I try to run OptiStruct to solve a simple sandwich panel bending test:
*** ERROR 14: Missing property # 2 referenced by CQUAD4 # 1
I saw other users experienced the same issue and reported it here in the forums, but I have already checked all the instructions given by admins to solve it and none of them worked, including assigning properties to all the components in the model.
<?xml version="1.0" encoding="UTF-8"?>
Any help or suggestion would be very much appreciated. I have attached the files I'm using in their latest version.
Thanks in advance and Happy New Year.

Altair EmployeeThickness is not assigned for the CQUAD shell element. Please assign and run again.
I assingned T=1.0 when defining the shell element property, ran OptiStruct and still got the same error messages.
there are a couple of issues:
-the core component is modeled with CQUAD4 shell elements, but the property assigned is PSOLID (hence the error message). Use 3D>solid map to create hexahedral/pentahedral solid mesh. But before this can be done make the top and bottom 2D face mesh match with skin (laminate) to ensure node to node connectivity between core and skin
-the BCs component does not have any material assigned
Use the Tool>Model checker>Optistruct to debug models.

Hello Ivan,
I've started from scratch and meshed the core element using solid map as you said. But when I mesh the skin element just before creating the plies using 2D automesh there is no connectivity even though I check the 'Keep connectivity' option.
