You seem to have overlapping surfaces, in that case I think you need to fix the CAD first, as Hexpress won't be helpful for this matter.

I resolved the problem. Now I do the mesh of two volumes, but for the third volume when I try to do the optimization phase the process failed.I try to modificy the optimization level but the optimization don't finish.

Check in the log file what is happening. It should point an issue with a specific edge or face.

There are concave cells and negative cells. How can i reduce them?

check where exactly this is happening and create local refinements maybe.

I imported the mesh in Numeca,but when i set the boundary condition of inlet there is a problem:

Erros:Can't read "ith_bc(phys_var;min_value;StaticPressureExtrapola ted,24,1,6)":no such variable"

hi "jackr84".......first of all check the boundary conditions-in HEXPRESS refinement is done on only on those surfaces which are tagged as WALL. Check the things out like geometry is clean & valid....if not try to clean in 3matic(no need of it, as you are saying that u were having x_t file; in hexpress itself u can clean), define proper taget cell size-TCS (TCS=initial_size/2^(refinement_level)), & hexpress has an built in algorithm which has success rate of 99.98% removing concave cells through default optimization step.

Dear DJ Santosh Kiran,

Maybe you can describe your problem such that people with experience in HEXPRESS/View can help you?

Best regards,
Colinda.
