Hey!
I made a mesh independence study in order to define the coarse mesh that throughs the same solution as a finer one. After knowing the element size that works to me, I had to make a change on the grid (changing it to an O-grid). Does this mean I have to do my mesh independence study again? Or could I extrapolate the results obtained before to my new case? (Geometry has always stayed the same). Thanks in advance. |

Yes, redo it. Changing grid topology is also an important change in grid characteristics.
For example, you can imagine I keep the same cell sizes but I draw them stupidly and put skewed cells everywhere such that the solution always diverges. |
