Setup the boundary condition database in the “bc dbase” folder (see Section 3.17).
In the .tcf file use BC Database to set the location of the database as follows. This command may also be used in the .ecf and .tbc files, however, by placing it in the .tcf file it automatically applies to both the 1D and 2D domains – this is preferred so as to keep all boundary conditions in the one database, unless it is desired to separate 1D and 2D boundaries.
