Dear all, I want to simulate the flow pattern in a random packed bed with spheres, but up to now i can only create geometries with regular packed particles by Gambit. Is there anybody knows how to create random arrays of spheres in a tube by Gambit, or by some other softwares while can generate mesh file employed by Fluent? Thanks a lot.

Regard, Eric

so, I have the same question please let me know when you have a answer
