Dear All,
I'm trying to proceed the simulation in a syphon. I'd like it to be transient simulation of two fluid - water and air. I tried to set opening in inlet with mass and momentum option - opening pres. and dirn and the same option for outlet but there is a warning "the solver failed with a non-zero exit code:2". The same warning occurs when I tried to set opening in inlet and boundary type in outlet. I have no idea where is a problem and how to fix i :<
