Good morning,
First of all thank you all for creating an useful forum to share our ideas and difficulties about CFD. Let's go to my problem.

First, I followed the tutorial which is described in https://github.com/enGits/engrid/wik...and-enGrid-1.2 ; which consists of a ball which receives moving fluid.
I created the model in Blender and the mesh in enGrids (version 1.4) with some problems, but I think I solved them. After exporting it to OpenFoam, I introduced the directory in my terminal and I wrote 'simpleFoam'.
The error messages which appear are:

Selecting incompressible transport model Newtonian
Selecting RAS turbulence model kOmegaSST
--> Upgrading k to employ run-time selectable wall functions
Backup original k to k.old
Writing updated k
--> Upgrading omega to employ run-time selectable wall functions
Backup original omega to omega.old
Writing updated omega
--> Creating nut to employ run-time selectable wall functions

Floating point exception (core dumped).

I don't know what these errors mean, so any kind of help would be wonderful!
I attach my enGrid model, in case it could be of help.

Thanks!
