2D problem automatically becomes 3D

Mughees · February 10, 2022, 01:46

I am doing a 2D airfoil analysis and when I generate mesh in the design modeler the control volume extrudes out into z-axis and the problem becomes 3D. I have set the analysis type to 2D and the thickness of the control volume while making 'surface from sketches' is 0. Kindly help me resolving this issue.

I have done 2D simulations for several other airfoils but never faced this issue.

The only time I've ever had this happen to me was when I was making a surface on a plane but one point was ALMOST 0 in the z dimension but not quite. ANSYS ended up thinking that extra length made for a 3D problem. I don't have a solution for you besides making sure your surface is exactly on one of the 3 planes with no part being in a 3rd dimension.
