Dear CFD Coleagues,

I generated unstructured mesh in ANSYS ICEM and output to ANSYS FLUENT but unable to read it in ANSYS FLUENT. I already set my boundary condition in ICEM also. I am simulating internal air flow. Below is the response when reading the mesh. I need help and would grateful for any support.

155975 nodes.
823071 tetrahedral cells, zone 25.

read saved file into the parallel solver.

I had similar problem in the past,


Have you used the "check mesh" within Icem?
Do you have any periodicity within your mesh?
Do you have different volumes within your mesh? are they connected in a conformal way?
Are you sure that you have also created a volume mesh?
