how can i set this outlet boudary conditon?

Guava Wang · May 14, 2012, 03:43

Dear all,

for my case, the inlet pressure and mass flow is know, and my propositon is to get the pressure loss during the fluid flow. there are four outlets in this case.
how can i set the boudary condition? please give me some suggestion.

thank you in advance.

best regards,

e.g. velocity outlet with 0 m/s

the outlet is given the velocity inlet boundary condition, and for the negative magnitude. hope that helps.

Guava,
You can use the mass flow inlet BC at the outlet, and specify direction of flow as "Outward Normal"
