Error in compressible flow
Hi all,
I am doing compressible flow(air) analysis. Inlet boundary condition = velocity = 39 m/s( constant mass flux) Outlet pressure boundary = 1 bar. After some time i am getting this error *** WARNING #060 *** DENSITY OUT OF BOUND DUE TO PRESSURE CORRECTION AT CELL 1 DENSITY= -1.8867E+00 LIMITER APPLIED Finally it says "Negative densities found at more than 100 cells" RUN STOPPED. Please give me some suggestions to sort this problem. Regards Krish |
Re: Error in compressible flow
1) search in the forum for "Negative densities found at more than 100 cells"
2) reduce the unterrelaxation for density |
