Force gauge vs. Computeforces
We are a couple of guys trying use DualSPHysics for confined internal flow without free surfaces using the outlet/inlet boundary conditions.
So far we have done two benchmark studies on poisseuille flow and flow around cylinder, but we do not get the same forces as when done with Finite-Volume Method. And theres even a big difference if we use the Force gauge vs. Compute forces to measure the forces on the same mkbound.
Does anyone know why this seems to be the case? What is the difference between the two force measure methods?
