Tried to run the simulation for a longer time to see if the backflow issue goes away. But it hast. About 40% of area has backflow throughout the time.nnResidualsnnOutlet pressure on water pipennAverage temperatures.It seems to be giving wrong physical temp, as the outlet of my water has less average temp than the entire water average temp, and this is probably because about 40% of the outlet area has backflow, and the backflow is happening at 300k.nnAlso, this simulation was rum by having time step size as 1sec , because 0.01s was too slow. Everything else in setup is same as sent in previous SS. Not sure whats going wrong and how to proceed.
