Hi everybody,
I am new to OpenFOAM. Currently I am using OpenFOAM-1.5 Can you please tell me various boundary conditions available for inlet and outlet in OpenFOAM. I went through the user's guide but found it wasnt comprehenssive enough.

Hi Ameya,

Yes you can specify inlet velocity. I believe you can also specify mass flow but I haven't tried that.

To specify inlet/outlet velocity you need to edit the files located in the "0" directory of the case you intend to run. You might wanna look at the tutorials, you will clearly see how to do it. I think the simpleFoam/pitzdaily tutorial has inlet and outlet velocity ("U") and pressure ("p") conditions defined. That would give you something to start with.
