Euler explicit for PISO
I'm simulating the flow in a rectangular duct with an oscillating patch on the duct floor, the aim being to observe pressure oscillations.
At the moment, i'm using pimpleDyMFoam with the following settings in the fvSolution file:
which should be equivalent to PISO, isn't it?
As my Courant number should be smaller than 1 for PISO accuracy, I'd rather go in an explicit time integration to speed up the computation. Yet, I cannot quite understand how to do that. Could anyone kindly explain how to implement an Euler EXPLICIT time integration?
Thanks in advance.
Is my question so dumb??
