Dear
I have built a stl file of pipe with rectangle section. Xmin is Volume flow rate and Xmax is symmetry. Do all Discharge enter the pipe?
Also, model has very error like "convective flux exceeded stability limit"
thanks

The symmetry boundary is like a wall with a free slip condition. If you want flow to exit the pipe, use an outflow or a pressure boundary at the XMAX
