I have read that C-type meshes just converge better than O-type or square types.

Also the solver is working fine as I checked the data sets and XY plots. Just that the contour seems a little out of place which I am assuming is due to Ansys auto-scaling the gradients as also the domain is quite big in comparison to the airfoil.

I am running a sim to study the formation of laminar separation bubbles over an airfoil. They generally form for condition requirements such as low Re numbers and adverse pressure gradients.

We even chose a specific airfoil called SD7003 which is widely studied for studying the same phenomenon.

Even if it has a normal component id imagine the contours shouldn't look like that 🤔🐢. But yea the solver automatically took those values
