Hello everyone,
I am stuggling with my simulation and i would like to know if one of you can give me a hand. I have a gemetry that consist in two ducts that inyect air to a chamber and i would like to study the distribution of temperature inside. i have started with a more simply geometry that just have one inlet duct. In this case, the simulation ran without any problem and i obtained some reasonable results. inyector simple 1.png un inyector.png However, when i add the other duct to the geometry and i tried to simulate with se same boundary conditions to the second inlet (i created a new patch), the simulation can not end. The results stops and i get the next. inyectordoble1.png inyector doble2.png The only change is in the domain, that is adapted to the size of the two inlet ducts If someone can help me i really appreciate it. Best Regards. Code:
