Introduction

This page contains alternate methods for XPSWMM to TUFLOW SWMM conversion and outlines common conversion issues and steps to troubleshoot them.

Model Conversion Without a XPSWMM License

The steps below are a guide on ways to convert a XPSWMM model to TUFLOW SWMM without a valid XPSWMM license. This process is not recommended and may cause issues in the converted TUFLOW model. For assistance converting an XPSWMM model without a license, please contact

With access to the XPSWMM Viewer and no valid XPSWMM license, the XPX data can be exported from the XPSWMM model, however, the DTM data and 2D model files cannot be exported. Follow the steps outlined here to Export XPX Data From XPSWMM.

Without a valid XPSWMM license, the DTM data and 2D model files cannot be exported from the XPSWMM model. To handle this issue, locate the files created the last time the XPSWMM model was run. These will contain the 2D model files and maybe a grid file. The grid file will be saved with the extension .tif, .flt or .asc.

There are two options for converting an XPSWMM model to TUFLOW without a XPSWMM license, depending on access to the XPSWMM Viewer.

With Access to the XPSWMM Viewer

Access to the XPSWMM Viewer allows you to export the XPX data from the XPSWMM model. This can be done by following the steps outlined here, Export XPX Data From XPSWMM. However, you will not be able to modify the 1D or 2D settings of the XPSWMM model. Therefore, you won't be able to export the DTM data or 2D model files from the XPSWMM model. To get around this you will have to locate the files created the last time the XPSWMM model was run. Using these files:

1. Navigate to the 2D/Data folder and locate the TUFLOW control files (i.e. *.tbc, *.tgc, *.tcf, etc).
2. Update the file paths in these files to represent the current location of the XPSWMM model if you do not have a grid file for the XPSWMM model, you will not be able to export If you don't have a valid XPSWMM license, but you do have access to the XPSWMM Viewer, but do not have a valid XPSWMM license.

   Without Access to the XPSWMM Viewer

   Common Conversion Issues

   XPX Tool

   Some conversion messages may be addressed/resolved by completing the Recommended Additional Conversion Steps.

   There are different levels to the conversion messages. An Error will abort the Convert - XPSWMM model from XPX tool and therefore may not generate a convert_messages.gpkg. There will be a description of the error in the tools log. Both Warnings and Checks will not abort the conversion process, and they will both be reported in the convert_messages.gpkg and the tools log. A Warning is more severe then a Check, however both messages should be reviewed to determine the cause.
