pimpleDyMFoam vs transientSimpleDyMFoam
I am currently in the process of simulating a radial pump using GGIs. Can someone please tell me the advantages of one solver over the other. They seem to be the only two available/relevant to my case.
So far I have noticed that pimpleDyMFoam runs 5 times as fast as transientSimpleDyMFoam, while the residuals for p remain higher.
I am trying to find the best solver that allow me to increase CFL at the limit I need.
Honestly: Back when I wrote that, I had barely started using CFD. Right now I am using Fluent and haven't touched OF for more than a year.
The choice between the two solvers is down to which OF you are using. Vanilla or extend. Personally I prefer PISO to SIMPLE. I think if you set the Outer Iterations in PIMPLE to 1, you end up with PISO.
