PIC; similar to that problem which I linked below (But I solved the negative density problem with mesh refinement)

Meshing and Turbulence Modeling Problems with Internal Baffles

I need to help for my case. I want to model an industrial-scale CFB boiler with internal baffles. I tried to solve it at different times and different meshing and modeling approaches. This is my geometry. My boiler has a one rectangular baffle + some u beams. [geometri1] [geometri2] When I tried to run with just a rectangular baffle, my problem can be solved. But I try to mesh for u beams, my simulation can’t be converged. So, I create a lot of internal (impermeable) surfaces that act as u-…
