I designed an air diverter and I am attempting to simulate airflow through it. There is a singular entrance on the bottom of the diverter, and the air is supposed to exit through the 5 exits on the sides. I am using an incompressible simulation with a velocity inlet (1 m/s) and pressure outlets (0 Pa). However, while meshing it returns the error “A multi-region mesh was assigned - this analysis-type requires a single-region mesh.” I have tried both standard and hex-dominant meshing with the same result.
