Problems when applied mDBC in NNewtonian flow condition
Hi
I am currently trying to apply the mDBC boundary to non-Newtonian fluids, but I have noticed significant numerical oscillations occurring in the particles after implementation.
It appears that particles are penetrating through the boundary, especially when using the Laminar + SPS viscosity representation for water. When using HBP non-Newtonian fluids, all fluid particles are excluded right from the beginning.
In theory, non-Newtonian fluids and water only differ in terms of the calculation of apparent viscosity. Why would such differences appear in mDBC?
Can someone give me some advice, please? Thank you very much!
