Apologies if this is in the wrong subforum, I didn't know whether it belonged here or in the running/solving subforum.

I have a problem when I run the command interFoam. During its reading of my U file I get the following error: 'Unknown patchfieldtype fixedFluxPressure for patch type patch'. Along with that I get a list of patchfield types that are available. However I have no idea which of these I am supposted to choose instead.

I'm not really experienced with openFoam. What I want is to have an inlet where I can define a velocity(or velocity vector) for where a fluid comes in. From my understanding an inlet should be of type patch, and using http://www.openfoam.com/documentatio...conditions.php I gathered that fixedFluxPressure for the inlet seemed to be the fieldpatch type I wanted, but it appears I cannot have this.

Does anyone have an idea what fieldpatch type I should be using to be able to define an inlet velocity?

Here is the U file incase you want to see it. I'm attempting to modify the "tutorials/multiphase/interfoam/angleDuct" tutorial.
