material define
 
hi,everyone i have a question, there is an error bellow: " absolute pressure limited to 1.000000e+000 in 255 cells on zone 2 temperature limited to 1.000000e+000 in 255 cells on zone 2 iter time/iter Error: Floating point error: invalid number Error Object: ()" The material is ideal-gas! But when i change the material density to constant, it can go through. the boundary is pressure-inlet and wall. thanks to anyone who can answer my question,please contact me through email

u can try following thing 1) check your initilization give some pressure to all zones 2) instead of pressure inlet try mass flow inlet BC then change to pressure inlet 3)keep very low under relaxation factor
