I think I have solved my problem. The mistake was that I left the line “FEATURES :=” uncommented. Now, to be exhaustive, here the exact commands that I used :
_ ./nozzle3d –resolution 5 –max-phys-t 10 : the calculation duration (measured time cpu) was 29.278s and an average MLUPS of 376.907
_ ./nozzle3d –resolution 10 –max-phys-t 10 : the calculation duration (measured time cpu) was 501.328s and an average MLUPS of 686.931
I ran these calculations today and the evolution seems good this time. Thanks a lot for your time and I hope this will be useful for someone.
Best regards,
Sylvain
