Cannot produce mesh

MFiX How to

Hello developers,

i am currently simulating a fluidized bed with simple geometry but cannot produce a mesh file in the very beginning, the settings all seem correct to me. Pls kindly take a look and see what went wrong, Thanks~

A few things:

  1. There is something wrong with the cylinder geometry. I recommend you use the procedural cyclinder instead of the implicit shape, and apply filters to flip the normals and translate the cylinder.
  2. The initial condition is incomplete, you should specify values for the entire domain (you only specified values for the bed region, you also need the freeboard region). There is a Background IC region that is always set by default to avoid this issue. If you delete the IC setting, please make sure you specify values for the entire domain.
  3. Your mesh is likely too fine (10 million cells). I would suggest you coarsen it.
