SubscriberI am simulating a hydraulic jump in a rectangular channel. Due to computational power constraints of my device , I selected SIMPLE scheme for pressure velocity coupling.
Which option should I select for "Volume fraction" spatial discretisation. Two options are available - Compressive and Modified HRIC. I already ran the calculations for few time steps with "compressive" and got some results but still I have a doubt regarding selecting the correct scheme.
I am attaching the screenshots of my Solution Methods and computer specs.

Ansys EmployeeI'd tend to use Compressive. It provides good accuracy but isn't too computationally expensive. I assume you're taking advantage of some parallel capability on your hardware?
