Packing particles in a tank

#1

Hi,
I am trying to fully pack particles in a STL file (as a stir ) in mfix-21.1.3 but got the following problems .
At line 1058 of file C:\ProgramData\Anaconda3\conda-bld\mfix-solver_1620448756094\work\model\des\desgrid_mod.f

Fortran runtime error: Index ‘-756’ of dimension 1 of array ‘dg_pic’ below lower bound of 1.

The attachment is my case.
rectangular_stir.zip (475.6 KB)

Kind regards

Please double check your inlet particle velocity. It is currently set to 100 m/s and it is pushing particles out of the domain. You do not have any outlet, so at some point particles are going to overpack and and your system will eventually “blow up”.
