Hi All, I am trying to solve a problem with periodic B.C. In order to do so I am reading a grid using the grid_in.read_ucd(input_file); command. Then I set up the boundary indicator for the faces I want to identify and use a constrain matrix to apply periodic B.C.
My question is there a way to read the grid with the boundary indicator set automatically by some reading grid function (if let say I set every face to be a different material) ? Thanks in advance Amir M.
