How can I simulate a turbomolecular pump using dsmcFoam?

[nimasam]

its a too general question
every simulation has three parts:
1- pre-processing ( generate mesh, assign boundary condition, define properties and so on )
2- processing ( run your solver which is here dsmcFoam)
3- post-processing ( see result at paraview and so on and compare results)

now what exactly your problem? in which part?

if you are beginner, i suggest you to read user-guide and run some test cases before start your case

Hi nimasam
Thanks for your reply
I am a new user of openfoam and I will try to start simulating by generating mesh and so on. I will ask my questions. thanks in advance
