ERROR 10157 - overlapping elements detected: <mesh_2dm_cell_ids>

Description

Two or more mesh cells share the same pair of vertices more than twice, indicating that the cells geometrically overlap. The cell IDs of the overlapping elements are listed in the message.

Suggestions

Open the mesh and inspect the reported cell IDs for overlapping geometry. Correct the mesh by removing or separating the overlapping elements and rerun the simulation.

This issue can occur if the mesh has been manually edited and mesh error have been introduced.
