I’m designing a nozzle and I am having some problems with calculation time.
I am trying to do an external and time dependent simulation but the calculation time is too big (over 20h) and my hardware is good enough (8 cores i7 3770 3.4-3.9GHz and 8Gb at 1866Mhz of ram .
I tried to reduce the computation domain and personalize the mesh. If I reduce the computation domain the calculation time decreases but not enough.
I also tried to disable “Optimize thin walls resolution “ option and “High Mach number flow” option. If I disable “High Mach number flow” option the calculation time reduces drastically but y need to keep this option enabled.
I am not sure if my personalized mesh has the correct dimensions.
That’s my actual mesh.
I’ll really appreciate your help
