Hi
before you start work, You must:
1- open the"porous media" in the "physics tab".
2- select one of the items with conditions to your model.
3- run the flow-3D model.
4- select option "drage function" in the "outout tab".
5- you can see the "normalized drag coefficient" in the "Text outpud" (in "Analyze tab").
so, you can use the "normalized drag coefficient",The calculation Drag Force.
Enjoy
