Hey guys, I have a problem with the combination between STL figure and Bed region. First it show me “Run divergence/stalled” then a “WARNING leg_bicgs.f:269, Warning: Singular matrix detected when solving for: EPp” and finally show “Negative gas density detected”.
Mi geometry model begin with a complex design, so I become to a simple design due to this “errors”. Also I modified the time step, maximum and minimum and only change the time error. Adicionally I build a solver and it use 8 core, but it show me errors again.
Attached my files of mfix and the STL file.
Best Regards
