compressible
hi everybody, im a student in uk, and as my final year project i have to simulate in ansys the flow within a convergent divergent nozzle, using ansys. i am having problems with convergence. I begin with artificial viscocity such as 10 or 100 and gradually reduce it to 0 after a 100 iterations, but i have no idea what else relaxation i should apply to get my convergence better. And the help file of ansys is a big mystery and its so difficult to find any documentation about this subject, so i thought about posting here. Any help would be great or just tell me what to read.... thanks
