Dear DR. Mahmoud
Thanks a lot for your kind reply.
However, even the the last result of pressure is still away from the
target pressure.
Neverthless, when running the same calculation for different compound, I
see that the target and calculated pressures are almost identical !!!!.
So, what do you think??
kind regards.
