Hi

I have very problem with boundary condition in openfoam. I think they are very confusing. I cant' understand difference between primitive and derived Bc. in openfoam!!!?? when I must use primitive Bc and when use derived ones?!!

also, I need to write a new boundary condition, but I don't know to use it, can anyone help me? it seems that I must compile it first but don't know to compile a new code. plz help me.
Thank you.

Well, the derived and primitive type BC's are defined in OpenFOAM's User's Guide. you may take a look at:

You can easily write your own BC in OF, there are lots of threads out there discussing about this. It would be better to take a look at them first.

Long story short, after writing your code and setting up the options, you can compile your code using GCC, with:

wmake
