Hi there,

I am working on turbo machinery problem.

My problem is hex mesh results.

My geometry has 3 volumes, namely inlet volume fan volume and out volume.

First I tried, hex mesh for inlet volume, tet mesh for fan volume and hex mesh for out volume.

for the above approach the results are really fine, and it gives good agreement with experimental results.

the problem is when I try with fully hex mesh approach for all 3 volumes, the results are not getting good agreement with experimental results.

The geometry is same for both cases, the mesh is different.

please give me some information, where I am going wrong?

Thanks for your information and time.


regards,
Sivakumar
