Troubles with simulation

I tried to run the simulation but it exited with error. There is no error message in the message window (messages below):

The subject of the simulation is to simulate the flow of air in front of exhaust slots. I have attached the model. Advice is appreciated.

Thx Marcus

It runs on my system. Please try upgrading to the latest version of BlueCFD, or alternatively the ESI installation of OpenFOAM. We did have a problem that looks like this that was caused by a conflict between BlueCFD dlls and those provided by FreeCAD. A workaround has been implemented, but I don't know if it works with the old version. Obviously also please make sure your workbench is up to date.

Thx for your feedback. I did how you suggested. Newest BlueCFD Core -> direct path in the settings / Paraview path reset / new cfmesh / new HISA etc. etc.. But nevertheless I got the following error message (no changes to the model):

Errormessage in the task window:

0.0: Checking dependencies...
0.0: Case writer called
0.1: Matching boundary conditions ...
0.3: Case written successfully
0.0: Solver started

324.2: Simulation exited with error

Errormessage in the message window:

in file X:/OpenFOAM-8/src/OpenFOAM/fields/GeometricFields/GeometricField/GeometricBoundaryField.C at line 184.

FOAM exiting

Do I interpret correctly that the solver has problems by identifying face0 ?

Thx for your help.

This can happen if changes are made to the model between generating the mesh and running the solver. Please re-do all steps from scratch to check the reproducibility of the problem from the saved state that you provided: Write mesh; Run mesher; Write case; Run solver. It runs fine for me.
