For the 2D domain, digitise objects where any boundaries are to be assigned. This includes connections to the 1d_nwk layer (ie. HX, SX and CN 2d_bc objects). Enter the attributes for each object (see Table 4 .24 and Table 4 .25) to define the type of boundary and the name of the boundary data to be extracted from the boundary condition database, or the connections to the 1D network.
Note: For 2D boundaries running along the perimeter of the code regions in either the 2d_code or 2d_bc layer, the 2D boundaries should be snapped to the region perimeter to ensure that the boundary is located along the edge of the active cells.
If using the 2d_bc layer to define the code regions, the same layer can be used for the 2D boundaries.
Create an empty .tbc text file (eg. my_model.tbc) and place it in the “model” folder.
Use Read MI BC in the .tbc file to read the 2d_bc layer(s) developed as follows.
.tbc file:
Read MI BC == mi\2d_bc_my_model.mif
In the .tcf file, use BC Control File to set the .tbc file as follows.
