Error when running

MFiX
#1

I get the following error when running my model, could anybody help me identify what this means?

At line 1058 of file C:\Users\Administrator\scoop\apps\miniconda3\current\conda-bld\mfix-solver_1613085458561\work\model\des\desgrid_mod.f
Fortran runtime error: Index ‘0’ of dimension 1 of array ‘dg_pic’ below lower bound of 1

#2

I got the same problem. I think it is because your grid size is too small compared to the fake particles(either you use cgp or PIC).
