However, I found that for the numerical schemes for the convection terms in the momentum equations of gas and particle phases, if I used Gauss linear, I found that the simulation is very unstable and always diverges. When I used LimitedLinearV 1 (same as that in the tutorials), it is stable but as you may expect, it is too dissipative. So I did not find a good choice for the numerical schemes for that. Anybody has the any comments for that? Thanks!
