Boundary condition
Boundary condition
Hi, Im new to Elmer and I want to write a UDF to give a velocity boundary condition at an interior boundary face. There two fluid zones and one is a porous media. At the interface I want to make velocity U.n=Const.*P(I)-P(c).In here P(I) and P(c) are pressures from each side. Please help. Thank you.

Hi Tharanga,
The methodology of writing User Defined Functions has been described in Elmer Programmers Tutorial(Chapter 1). Also, you can get some more information at Elmer Solver Manual(Chapter 13). After you begin writing a minimal user defined function/solver, you can put forward your specific question again in the forum.
