12d’s drainage module integrates directly with the XPSWMM/XPStorm interface. This simple transition between packages allows teams to combine the functions of 12d’s terrain and pipe design capabilities with Innovyze’s hydrology and hydraulic assessment tools. The process for exporting the 12d model data to XPSWMM/XPStorm and then taking the results back into 12d is outlined below.
Replace the existing swmm.dmf file located in the 12d directory on your computer with the one provided with these instructions (or you can download it here). This file controls the mapping between 12d and XPSWMM/XPStorm and can be edited in a text editor if required.
Locate the .tin0 files for the TIN you wish to import.
Check the Infiltration and Rainfall has come across from 12d.
Apply loss coefficients to system where required.
Once the model has been solved, the updates and resulting HGL can be exported from XPSWMM/XPStorm and brought back into 12d to finalise designs.
