Partial cells

Hi,

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 ?

 

Thanks,

Alex
