Fine Level Coefficient Matrix
 

Hello,

I've tried searching the forums for this and found some but not quite detailed answers. I get this error message when beginning to iterate in Fluent:

"couldn't allocate fine level coefficient matrix"-"error object()".

I've read it may be something to do with memory and/or the type of solver used.

Can anyone please elaborate? Kind regards NK

Hi,

It may be owing to negative volumes in your mesh. try to reduce the number of control volumes and importing the mesh file again. Once this is done check the mesh for negative volumes if there are any, remesh the geometry.
