Hi everyone, I am solving full coupled Lagrangian particle tracking in CD nozzle.
I get a very weird error, which is The ANSYS CFX solver exited with return code 4 and without more error messages. The reason for the weird is that my simulation worked very well before I used the particle user routine. When I first successfully used the particle user routine, the solver exit with return code 4.
After that, I cannot make the simulation work again even without particle user routine. Furthermore, it shows the same error that the solver exit with return code 4 in the case of single-phase. In addition, all the simulation failed in my local windows can run in graham server. Does anyone know the reason?
