Hi every body
I'm trying to simulate the flow field in a cylinder, containing some spherical solid bodies with a random arrangement . can anybody tell me what will be the true strategy for creating the geometry?

1. subtracting the volume of spheres from the volume of the cylinder that results to a mesh with high skewness

2. meshing entire of the cylinder , considering the spheres as solid domain and meshing them separately, i tried it , but after postprocessing, I saw the fluid passes through the inside of solid bodies whereas the fluid should pass over the spheres.

if none of them is the true, so what will be the true way for creating and meshing the geometry that result to a true flow field?

kind regards

hey friend,

I think you should try multiblock grid around sphere surface. & U must substract sphere from cylinder. This will be helpful as per my opinion.
