Set frictional contact in Non-Newtonain flow
Hi, does anyone know how to set frictional coefficient for fluid-boundary interaction in SPH? Particularlly, I am using Non-Newtonian solver and "ViscoTreatment" = Constitutive eq.
I understand that if I use Newtonian solver, choose "ViscoTreatment" = "artificial viscosity" and set "ViscoBoundFactor" to a value larger than 1, then I am kind of having created a frictional boundary. However, I don't know how to set this friction in "Non-Newtonian & Constitutive eq".
Is there modification I can do in dynamic boundary condition? But I didn't find anything in DualSPHysics wiki about that. I also tried to couple it with CHRONO since CHRONO has Coulomb frictional contact defined in it. However, since there is no floating object inside my model, the error reads:
So I guess CHRONO is also not a correct way to solve the problem.
Thanks everybody who join the discussion in advance!
