quadUP elements not supported following quadrilateral meshing

Post by MUz » Wed Jan 04, 2023 10:55 am

Hello,
I have created quadrilateral meshes using

Code: Select all

op.mesh('quad', etc.
and am able to successfully assign 'tri31' elements of 'ElasticIsotropic' materials.
When I try to assign 'PressureIndependMultiYield' materials, the routine crashes and I receive an error message "Restarting kernel..."
Moreover, if I try to assign 'quadUP' elements, I receive the error message "element quadUP is not currently supported in mesh".
Could someone provide guidance as to why this is occurring? I was not able to find any reference regarding limitations in assigning materials and elements to quadrilateral meshes. Or am I missing out on something else? Thank you.

The mesh command doesn't work for all element types, and it will only mesh triangular elements (for some quad elements, we could define two nodes at one location).

Anyway, you may want to try the block2D command.
