I want to calculate the heat transfer and pressure drop through a packed bed, so firstly , i create a random packed bed using DEM method,then i got the spheres coordinates. Secondly, i transfer the geometry to ICEM and mesh.
There are some problems i can't continue:
1:the contact point distort the mesh;
2:i use tetra+prism to mesh ,but the quality is too low to calculate.
3:there are so many cells for only 100 spheres, which took too much time to mesh.

So i want to know if anyone can share a more convenient method to mesh the spheres and if i have as up to 10000 spheres, how to mesh using ICEM?

Thanks!
