Command run in terminal but not in QProcess while PATHs are inserted

[Ginsengelf]

Hi, have you tried to use the complete path for fluent3DMeshToFoam as the argument for QProcess, instead of editing the PATH variable?
So for line 4 something like:
myProcess.start("/usr/local/bin/fluent3DMeshToFoam" , QStringList() << "<mesh address>");
or whatever the absolute path is.
