Reply To: Cuboid Geometry-Drag and Lift


Hello Adrian,

Thank-you for the reply.

Yes,actually I mean the flow around the cuboid shapes.

As per my above comment, I have described my drag definition at the inlet and outlet. However, I am getting infinite value at the inlet and outlet.

I tried setting the drag definition even for bstep2d/3d (Cuboid Shape geometry) and found similar infinite value for drag coefficient and lift. That is the reason I asked whether Drag force is calculated using Stokes Law. If it is calculating by Stokes Law, the Radius of Curvature in the cuboid geometry would be taken to be infinite.

So, could you please help me to imply the drag and lift definition for cuboid shapes?
