Extrusion of element type QUADSHELL4 error

[garcs2]

Hello,

I'm currently trying to extrude a mesh of a 2D slice of a core for heat conduction. The mesh was generated in cubit and I'm attempting to extrude it in MOOSE. Below is an image of the mesh in paraview:

All I need is to extrude the mesh in the z direction, with some slight variation in the extrusion layer heights. To do this I use AdvancedExtruderGenerator and get the following error:

Extrusion is not implemented for element type QUADSHELL4�[39m```

Is there any way around this? Am I to understand that QUADSHELL4 isn't supported for any extrusions in `MeshGenerator`?

in cubit you should specify the element type to be QUAD4 instead of QUADSHELL4
