This Wiki page outlines manual steps for the conversion of an XPSWMM model to TUFLOW. A more efficient, semi-automated approach is available using XPSWMM XPX files. It is recommended instead of this less workflow efficient method. For information on the semi-automated approach, see <u>[[XPSWMM_to_TUFLOW-SWMM | XPSWMM to TUFLOW SWMM: Automated (Recommended) Approach]]</u>. <br>
 
XPSWMM is a flood and urban stormwater drainage modeling software developed by Autodesk (previously Innovyze and XP Solutions). The XPSWMM solution uses EPA SWMM for its 1D calculations, dynamically linked to TUFLOW for its 2D calculations. The software functions within a custom build Graphical User Interface (GUI). Unknown to many XPSWMM modelers, during simulation, XPSWMM processes its inputs into TUFLOW files and also calls TUFLOW for the 2D calculations. As XPSWMM uses TUFLOW for its 2D engine, like-for-like results can be achieved using this software.

Common user feedback suggests the XPSWMM GUI is useful for simple modeling projects; however, it can become cumbersome and workflow inefficient when dealing with larger datasets and/or a large volume of different scenario and event simulations. In response to requests from USA XPSWMM users who want to convert XPSWMM models into a native TUFLOW format, TUFLOW linkage with 1D EPA Storm Water Management Model (SWMM) was added as a supported feature in TUFLOW 2023-03-AD release. The modeling workflow in TUFLOW differs from XPSWMM, as TUFLOW modeling is integrated with QGIS (Geographical Information System) GIS software. This is, however, a net positive. GIS integration is well-suited for working with larger datasets. Additionally, the structural design associated with TUFLOW modeling makes its general workflow extremely efficient, particularly for the automated management of multiple scenarios and events.
 
If you are building a TUFLOW SWMM model from scratch, not from XPSWMM, please refer to the <u>[[TUFLOW_SWMM_Tutorial_Introduction | TUFLOW SWMM Tutorials]]</u>. Tutorials are provided for the following topics:

'''If you are using this example conversion dataset, please rerun the XPSWMM model in the location where you save the dataset before beginning your own TUFLOW model conversion.''' Rerunning the model is necessary because XPSWMM will write TUFLOW files during its preprocessing, subsequently defining the correct file path information (for the location where you saved your files) in the newly written TUFLOW files. We also recommend creating your own TUFLOW model in a different folder from the provided TUFLOW dataset so you can easily compare your model against it.<br>
 
== TUFLOW Licensing / XPSWMM Discount ==
If you are an existing or past XPSWMM perpetual license owner who would like to purchase a TUFLOW license, please contact <u>[mailto::sales@tuflow.com sales@tuflow.com]</u>. You may be eligible for a XPSWMM / TUFLOW discount in recognition of past royalties Autodesk paid TUFLOW if you previously purchased an XPSWMM perpetual license.
