ICEM CFD Prism errors
 

Prism keeps failing with the output:

done smoothing marking triangles triangle xxx xxx xxx seems to be in the wrong family triangle xxx xxx xxx seems to be in the wrong family

where xxx are numbers that I assume correspond to the nodes connected to the triangle. I've generated and regenerated meshes for this geometry (using the same meshing parameters and method) and the number of triangles in wrong families varies each time. On one of my meshes there is only 1 triangle labeled as being in the wrong family. How can I identify it and assign it to the correct family or otherwise get prism to run on the mesh?

I tried adding nodes to a subset by element number, but only 1 of the numbers from the message is a valid node number. The mesh has no unconnected vertices.

Possibly resolved.

It appears prism won't run if you set the number of surface and volume smoothing steps to 0. I set them to 1 and it runs.
