hi, everyone. I am running a case with one inlet but two outlets. The thing is that how should I set the flow rate weight, since I can not tell how much of the percentage of inflow will go through one specific outlet. What should I do? Thanks in advance.

What do you know about the 2 outlets? if you know pressure to which the flow is exiting to, you can define pressure outlet conditions. If you know velocity, you can define inlet conditions with flow leaving the domain.
Maybe you guess at the exit pressure(s) and then find out how much mass exits one are and how much the mass exits the other. Then run the solution with 2 outflow bc's and the corresponding flow rate weighting. Or maybe you can estimate it with simplifications. That depends on your type of flow. |

Could you tell me what is that you have decided to do, and what kind of problem you are solving for?
