Hi I'm new entry in this forum.
I'm doing some simulations for my thesis work and in order to identify a grid dependence in the problem, I have modifid grid, incresing number of cells and wall ramming of grid.
To simulate turbolence I'm usig SST model.
When I run the case with high ramming of grid, the simulation stops with this error:

--------------------------------------------------------------------------------------
A wall has been placed at portion(s) of an OUTLET |
| boundary condition (at 100.0% of the faces, 100.0% of the area) |
| to prevent fluid from flowing into the domain. |
| The boundary condition name is: outlet. |
| The fluid name is: Fluid 1. |
| If this situation persists, consider switching |
| to an Opening type boundary condition instead.
---------------------------------------------------------------------------------------

Has someone any ideas to fix it?
Thanks
