May you explain me how to run a computation Code_Saturne with gdb?
I do not remember whether this feature was available in version 5.3 though, and in any case it may be less mature. But 5.3 has been retired since September 2019, so I recommend upgrading to a more recent version (either 7.0, the current stable version, or 7.3, which is a preview of the upcoming v8.0).
