All I have managed to create is shown in attachment2. I know that for patch mesh the geometry should be divided in to regions containing 4 boundaries. But I am not able to think of a way to apply this so that I achieve the same result as in attach1.<br><br></div>Can you please provide some insight in this.<br> <br></div>The reason I need a mesh similar to the one shown in 1 is because the bottom boundary of the mesh changes in the simulation which I am running and causes the cells to become highly skewed. I don't think this problem will be present with the mesh structure of attach1.<br></div>
