Hi,

I want to do some modification to Source of Momentum FU/FV in Telemac2D(Subroutine prosou.f).
The definition of it is
FU%R(IR) = FU%R(IR)-UBUS(1,I)-%R(IR))*DBUS(I)*UNSV2D%R(IR)/MAX(HN%R(IR),0.1D0)
I have try to use another equation but show error information 'EXCEEDING MAXIMUM ITERATIONS'.
Then I found out that even a lightly increase(For example Multiply FU/FV by 1.01) would cause the problem of 'EXCEEDING MAXIMUM ITERATIONS'. While decrease FU will cause no problem.

I am trying to find the reason why this variable is so sensitive, is there anybody know about this? Thanks in advance!

Best Regards,
Bin

Hi,

This problem has sloved.

I use other parameters to replace UBUS and VBUS. It seems that any change to UBUS/VBUS in the calcualtion of FU/FV will case this problem.
