I've a incompressible steady state model I don't get to run. The error message is:

ERROR: Failed to post close command error 1726
ERROR: unable to tear down the job tree. exiting...

I did attach the model for better investigation.

Thx a lot for help.

Changed mesh density to 5mm for base and 0.5 for refinement. It worked and converged

Hi, thanks a lot. But why did it not Work with the previous mesh size ? Out of memory ? .....

For me your model works, did the run with your settings, no changes.
Convergence is pretty fast, 65 iterations.
simplefoam consumes approx 2 GB RAM in total, should be no problem.
Strange p-residual...

I don't get it. Despite me nobody seems to have troubles with MY model

Again I have:

13:33:56 ERROR: Failed to post close command error 1726
ERROR: unable to tear down the job tree. exiting...

It's hair-pulling

Quoting from the post "CfdOF workbench information: Please read this first":

[*] On Windows, there can be issues with conflicting MSMPI versions. This is usually indicated by the following error:

Code: Select all

ERROR: Failed to post close command error 1726
ERROR: unable to tear down the job tree. exiting...

The best remedy is usually to uninstall and reinstall the OpenFOAM (or BlueCFD) package, making sure to run the installer with administrator privileges if possible. If asked, answer 'yes' to reinstalling MSMPI.
