Hi everyone,
what would be the best way to carry out a one way couple simulation in which the particles "feel" the flow, but the flow is unafected by the particles?
Would setting alphamin to 1 achieve this correctly?

Hallo Andres,
Hallo Andres,
I did not test this but I think should work:
you can try additionally comment this line
https://github.com/CFDEMproject/CFDEMcoupling-PUBLIC/blob/master/applica...
in cfdemSolverPiso in order to switch off a forcing term (due to presence of particles) in the momentum equation. And then recompile the solver.

You can achieve the same by
You can achieve the same by setting KslLimit to 0 in implicitCoupleProps, although Alexanders approach would be slightly faster.
Greetings,

1way coupling
The correct way to do this is to use the noDrag model to discard forces on the CFD side only.
This is also what the approach suggested by Alexander does in the end.
The approach suggested by paul will also affect the forces acting on the particles and might, therefore, not lead to a real one-way coupling.
