PROBLEM WITH LEVEL SET: DIFFERENCE BETWEEN MATLAB AND ELMER

Post by Andrea_P »

Hi,
I don't understand why the results obtained in Elmer are pretty different from that ones of Matlab. I have used the same formula for the velocity profile but as you can see from the attached images, there is discrepancy. Particularly, the Elmer profile starts with the right form and next it decreases downwards. I attached everything, thanks in advance for your help. Mesh link: https://we.tl/t-IahP1yLJ2U. I have tried to refine the mesh, but I obtain the same behaviour.
Regards,
Andrea
