Hi everyone

I am having some kind of problems doing a fu***** simple mesh of a sphere. I have tried dozens of domains and bodies of influence, as spheres of influence as well.

None of those work well! I am trying to study the drag coefficient on a 45mm diametre sphere, which should give me 0.5 of C_d.

Sadly, I can only reach around 0.2.

I have already done:
- cylindric domain with a simple sphere

- cylindric domain with body of influence

- sphere domain with a lot of sphere of influences

- and so on.....

Can anyone give me some guidance on this, please? Like, for what true domain should I focus on and what kind of elements of geometry should I compute (triangles, tetra, hexa).

I can provide deeper info about what I have done if it helps.

Thx you
