CFX Total force problem
I have been doing a 2D simulation of an ahmed bluff body. Meshed in ICEM and run in CFX. ive tried a veriety of different meshes and they all seem to affect the total force as if the ''edges'' are part of the geometry. This problem can be seen in the attachment. The velocity and pressure contour plots seem fine.
If any one can help me i would be greatful as im new to CFD!
Force is roughly pressure * area, so the total force will depend on the area of each "face" in the contour plot. When looking at force you usually look at an area weighted integral on a wall boundary.
