I am confused about the momentum coupling options in CFDEM viz implicit/explicit. Following are my questions.
1. what is TotalForceImp displayed in the cfdem log
is this done implicitly? sum(mesh.V()*Ksl.internalField()*(Us.internalField()-U.internalField()));
I ask this because of the next question.
2. On CFD side I have momCoupleModels selected as implicitCouple
While on DEM side for the resume file, I have: fix cfd2 all couple/cfd/force
How is the force calculated in this case? is it done explicitly?
does this have to be couple/cfd/force/implicit?
Thanks and regards,
Vinay
