I am trying to follow the Openfoam user guide but I'm stuck at the first tutorial 1. In fact, when I try to run the blockMesh command (using the administrator account), the following appears:

Writing polyMesh

--> FOAM FATAL ERROR: Failed writing polyMesh.

From function blockMesh in file blockMeshApp.C at line 325.

FOAM exiting

I tried to follow instructions given in this thread 2 but none of the two here proposed can help me.

Any advice?

Thanking you in advance, Filippo

    $\begingroup$ You're using the admin account... OK. But are you running it in your home folder? Somewhere else? What is the path where you run blockMesh, and what is the full command you run? $\endgroup$

  • $\begingroup$ Dear Filippo, welcome to SciComp. The question you're asking is more related to the installation of OpenFOAM itself than to the numerical analysis/algorithms behind it. I think you're better off contacting your local sysadmin or the OpenFOAM community. $\endgroup$

I would check if you are in the proper case directory and not in any other directory, such as $CASE/constant/polyMesh or something similar. Have you copied the tutorial from $FOAM_TUTORIALS to your home directory or somewhere else, where you have proper permissions to read and write? I generally suggest not to use the administrator's account for your daily work.

Hope this helps, otherwise please provide more information (OpenFOAM version, etc.)
