Coupled Algorithm in OF
 
Hi, everybody:

I don't know how many of you know the coupled algorithm in FLUENT. It combine the Ueqn and Peqn in matrix level, and solve U and P at the same time, which gives better stability and robustness.

Does anyone have tried to imply this coupled algorithm in OF?? I am thinking about combining the Ueqn and Peqn, but I think it is more complex than i expect.

Dose anyone have good ideas?

thank you in advance.

Well. Seems some have heard of it and even work on it. Have a look at http://merida.csi.tu-darmstadt.de/op...fAbstracts.pdf page 165 and also Jasaks training presentation about inter-equation coupling. The presentations will hopefully become available soon
