chegdan will become famous soon enough
I'm attempting to adapt the interFoam solver to incorporate cyclic boundary conditions. I have had a look at the ChannelOodles solver and added several files (mainly the createGrad.H and writeGradP.H). The solver was able to compile and I have run the damBreak case with no problems, receiving similar result to the interFoam solver. However, when I apply cyclic BC's to another case, then there are problems. I must choose a ridiculously small courant number (1e-5) to even have continuity converge and even with that the pressure gradient still diverges. I will attach the solver and my case to see if anyone can help. Please take a look at it, see if there are any issues and maybe make some comments.





Thanks for any help that can be given. Also, I will be sure to share any knowledge gained with the community.

Dan

asaha is on a distinguished road
I took a quick look at your case file, may be some thing is missing in your pd file and see if reducing the deltaT further has any effect on the solution.
