river flowing to NW direction

[edith]

Hi,
I am having problems with setting analytical point source. Do i understand it correctly that to set a direction of the inflow water i have to set Dsrc (0 toward east and 1 toward north. or when 0.5 then it would give NE wind?) and Qbar (when positive then along u or v direction and negative to -u and -v direction).

So when i put Dsrc = 0.5 and Qbar= negative/positive mass flux i get flow in NE or SW direction?
But using this i can not figure out how to make my river inflow go to NW direction (as well as it would be impossible to get SE directed flow?). I must have missed/misunderstood something or is it really not possible to do it analytically?

You will need two sources, one going west and one going north. Each source is along one grid face.

Kate,
thank you for the reply. i will try that.
