I'm simulating a fully developed flow using pimplefoam (I've read that now includes the channelfoam solver) and cyclic BCs on inlet/outlet; but i'm facing a strange problem. I have a pressure's residual too high (about 1) and it doeasn't decrease.
Here what i've done: -consider a finer mesh -change fvsolution and schemes -change Courant number (lowered to 0.5) and time step -change initial values The problem hasn't been solved and I don't know why. I've made the same setting long time ago and it worked unfortunately i lost that case files. |

Here teh remaining files. Btw I've used the kEpsilon method with a coarse mesh.
