I would like to ask you a question about partial cells. From my understanding, they are cells that lie partially in the solid and partially in the fluid.
If you have only partial cells in a flow passage where there are high gradients it's not good because you would get low quality results.
For what concerns the boundary layer, I've never seen a situation where you have only fluid cells, but, from my understanding, the program will always turn out creating partial cells at the boundary between the fluid and a wall.
So my question is:
what are partial cells used for ? Are they used to calculate the fluid at the boundary layer ?
Do you get the sane level of quality respect to the results you'd get with fluid cells ?
