PDE for mesh element matrix not valid

I am trying to import a mesh into the pdecreate command in matlab but i keep getting error that the elements are not connected correctly. The code is attached.

How do i get the element matrix to be correctly input into matlab?

Hi Anosh,

The nodes matrix in “untitled.m” has all Z's at 0, while elements are tets (4 nodes).

In a solid geometry, all nodes sit in the same plane, and thus the definition in “untitled.m” is invalid. Please make sure the input data for “geometryFromMesh” is consistent for either 2-D or 3-D case.

For details, refer to the documentation: Create 2-D or 3-D geometry from mesh - MATLAB geometryFromMesh (mathworks.com)

Hope this resolves your issue.

Prateek.
