I have installed OpenFOAM on WSL2/Ubuntu as described here and here. created a non-root user

adduser ofuser --disabled-password
passwd -d ofuser
adduser ofuser sudo

logged in as the ofuser

su - ofuser

and then

source /usr/share/openfoam/etc/bashrc
export WM_OPTIONS="$WM_ARCH$WM_COMPILER$WM_PRECISION_OPTION$WM_LABEL_OPTION$WM_COMPILE_OPTION"

gave the user full privilege on the case folder

sudo chmod 777 <PartentFolder>/*

but when trying to mesh with

blockMesh -case <CaseFolder> -blockTopology

I get the error message:

you may find the archived version of the case folder in the attachments.

P.S. Funny enough, I had posted a similar issue here, ages ago!

Hi,


I have found several posts on this forum about the error:


'FOAM FATAL ERROR: exec(wmake, ...) failed'


They are always unsolved (apart for the more or less trivial ones, where the user just forgot to install 'make'. The cases where the user did install all prerequisites remain unsolved.)


Did anyone ever solve it?


Thanks!!!

Never mind, it turns out that the Debian package for 2306 does not contain wmake!
Upgraded to 2312 and everything is fine

Correction: the solution, in my case, was to install openfoamXXXX-dev.

For some reason, it was automatically installed for 2312, but not for 2306. Adding it solved the problem for me.
