Maybe I'm asking for too much but could you do something similar with the SIMPLE algorithm? I would really appreciate it. Regards, Alex __________________ Web site where I present my Master's Thesis: foamingtime.wordpress.com The case I talk about in this site was solved with chtMultiRegionSimpleFoam solver and involves radiation. Some basic tutorials are also resolved step by step in the web. If you are interested in these matters, you are invited to come in!

Hi Alex,

in the next days/weeks I will investigate time into the SIMPLE and PISO algorithm too. Yesterday in the evening and I had time to do it. Normally there is not much time to do something like that. At the moment I am still working on the PIMPLE blog. I updated some equations etc.

Greetings to all!

Just thought to let you know that these wiki pages exist:
@Tobi: Any chance those two blog posts could be copy-paste-adapted to openfoamwiki.net? Although, keep in mind the license the wiki uses :

But first I will check out the hints on my blog (: and extend it to complete it. After that I will move / copy it to the wiki. I have to look to the license (: wyldckat likes this. __________________ Best regards, Tobias Holzmann Some interesting OpenFOAM tutorials, publications and videos on www.Holzmann-cfd.de OpenFOAM Beginners should check out the new wiki on wiki.openfoam.com A list of some active OpenFOAM contributers can be found »here« A book about the basics of »Mathematics, Numerics, Derivations and OpenFOAM« can be found on www.Holzmann-cfd.de
