ansys to foam and solve with dsmc
 

hi
I am beginner in the openfoam and decide to solve a problem with dsmc code.
I create my body in catia and then import it to ansys and I use workbench to create my mesh file(.msh) and then I create a newfolder and create (0,constant and polyMesh,system) but those are empty and then I put my (.msh)file into my polyMesh then run fluentmeshtofoam and I see this:
[hadi@hadi polyMesh]$ fluentMeshToFoam hemishpherical.msh

now I don't know what I have to do for create the for example fvsolution or iDof ,rho,momentum and other the files?
