solving pressure equation
Hi all,
I am simulating wake vortices in ground effect and I'm using the icoFOAM application. I would like to know why it solve twice for p at each time step. I have no error message or warning just the following output when I'm solving. Code:
Courant Number mean: 0.0258412 max: 0.99935 Thank you, Pascal |
Hi Pascal,
"Solving for p ..." shows up twice because in icoFoam's standard setting the number of pressure corrections in the PISO loop is set to two. If you wish, you can change this at the bottom of the system/fvSolution file where it reads Code:
PISO |
While your at it, you should do some reading on how PISO works in Ferziger/Peric or the original paper by Issa and Olivera...

Thank you for all the information
