I am new to SimScale, and currently attempting to simulate multiphase flow (water and air) in a static mixer, which I will next build with my own hands! My hope is that SimScale will provide useful insights into the designing phase, (e.g. shape and number of mixing elements required to achieve good mixing without creating too much pressure drop).
So far I’ve managed to resolve my simulation issues by reading through the forum, which has been very helpful, but now I face the following question:
how can I make my simulation less computationally painful?
My previous run ran for 172 mins before being canceled, as the maximal allowed time had elapsed.
I already decreased the Delta t (to 0.001 sec), as advised.
I can always re-run with a smaller time step, but I feel like it shouldn’t take that long, and that there is something making it abnormally long.
I’d appreciate any comment or idea on how to make this less painful.
