hi all,
i want to run a periodic channel with a fixed pressure gradient in channeloodles. In the transportProperties dictionary there is only an entry for Ubar but not for gradP. In the file createGradP are the following lines: IFstream gradPFile ( runTime.path()/runTime.timeName()/"gradP.raw" ); I am new to OpenFoam and to C++, do I have to create a file named gradP in my start time directory? If so, how must it look like. Thanks for any answers, Nikos |

Hi Nikolaos,
I am new to openFoam too, i am also running simulations using channelOodles solver, for my understanding to fix a pressure gradient, you have to modify channelOodles.C, by adding a linear pressure gradient that can be a constant added to the momentum equation in the streamwise direction, and then u calculate Ubulk that will oscillate around a mean value. I didn't try it yet,so please anyone correct me if i am wrong. Hadi |
