I working on the mixer module in comsol multiphysics and each of my runs takes so long such as 14hours or more. even frozen rotor mode takes 2hours. how can I improve my file and decrease my solution time?
I found these links, I hope they will help, how to solve the problem.

Thank you. I saw them before, but they didn’t help me. I found another way to decrease solution time with converting 3D model to 2D assymetric model. I do it but it has an error in mesh step.
Maedeh Asgharian Asaalamuwalaiqum you can try the following links , i hope it helps you a lot
Jazakallah khairan.
Maedeh Asgharian Use high-performance computers and assign more computer cores to the COMSOL multiphysics. Use the following threads :

thank you Sajid Ahammed and Pawan Kumar
I read these pages but I found that the comsol running time of tutorials is a few minutes such as 4minutes(that write in the documentation of mixer in comsol) but that running in my system with 8cores and high RAM takes 5days!!!I want to know why would I do?
