volume mesh is generated but when starting solution it is showing volume mesh is not there

Hi,

I am running  a vehicle thermal simulation with wind tunnel in altair hy[perworks cfd 2022.2.

Volume mesh is generated, but when I tried to start to solve the solution it is not working.

It is showing, volume mesh is not there.

I even checked entity count and in quality report. 3d elements are there in those .

please let me know, what is the issue.

Regards,
