cfx steady simulation

maheshchamarti · June 20, 2017, 09:04

iam trying to simulate a two domain one statinary and one rotating domian. the stator has 24 blades and rotor has 12 blades. there are two stator blades in the stator mesh and one blade in the rotor mesh. so passages in 360 is autocalculated by cfx as 12. but when i set up the simulation an error pops up in the cfx pre saying value of no of passages in 360 in object/turbo post data/turbo post component:R1,0 , violates its lower bound 1. also my simulation keeps crashing on high mach no values. i have tried to initialize in different ways but it keeps crashing in less than 10 iterations.

do all the tutorials for two domains and rotor/stator cases. You will probably find your mistake after that.
If not, post screenshots, your CCL and your OUT file.
