How to monitor Drag around a porous cylinder
 

Hello member,

I am simulating a flow around a porous cylinder. The interface between the cylinder and the other bodies is not a wall, but an interface, because the cylinder is not a solid, but a porous body.

The problem is that it is not possible to monitor the Drag at the cylinder surface since its surface is an interface not a wall, and the drag can be monitored only on a wall.

Have you got any suggestions?

Thank you

I also want to get drag force at the porous surface . Did you find a solution to it?
