Hi everybody :-)
I'd like to use PRESTO (Pressure Staggering Option) in OpenFOAM. I know that this option is a preset in Fluent, but I couldn't find it in OpenFOAM. I appreciate any help/comment. |

Thanks for your reply Nima. I'm looking for a more accurate pressure solver, for swirling flow applications. So do you have any suggestion?

The results are completely different compared to what I get by Fluent. I have 2 inlets and 2 pressure outlets (with different pressures)! but the solution converges to "2 inlets, 1 pressure outlet, and 1 pressure inlet".

So what option is available in OpenFOAM that is similar to PRESTO! in Fluent?
I am trying to solve a case with buoyancy driven flow. |

IF results are "completely" different it means you're using wrong schemes in OpenFOAM, or you're doing something very wrong.
But, if PRESTO is a must, you can code it and we can use it in future too... |
