Is it possible to export a C written code to OpenFOAM?
For example, if Im looking forward to expressing a variable boundary condition (let's assume a senoid), can I write it in C and use it as an input to OpenFOAM?
Like in Fluent there are the UDF's (user defined functions).

Thank you, very much.

Regards.

There's two ways to do it:
It'll depend on what type of bc you have (fixed, gradient, mixed), but you could take one of the timeVaryingXXX boundary conditions from OpenFOAM as a starting point and define your things as 'extern C' binding (presuming they are in an external library.

The other possibility is just to compile your existing C code as C++ as part of your new OpenFOAM bc.
