Hi, guys

I'm doing a simulation relating to a gas flow inside a pipe. There are multiple inlets and when I tried to calculate the result it keeps telling me an error saying "dot product of flow direction and area normal is 0" my boudary condition is set to be mass flow inlet and I can't find a way to change the flow direction or anything else. Any suggestions? Thanks!
