about dynamic mesh?????
I am trying to simulate twin screw pump by using ANSYS-FLUENT and I used dynamic mesh but I have a problem when I preview mesh motion and I got negative volume. before that I used ANSA for intial meshing of the model I think I have to smoothing the mesh but I couldn't, please can you suggest me how can I have to solve it and if you know any other refference on screw pump simulation please tell me.
