General Notes

This is a patch release for TUFLOW 2025.1. This release fixes an issue with arch bridges in ESTRY causing a pre-mature model exit, an issue with TIF inputs that use very large ‘no data’ values, and a number of output bug fixes. For more details and a complete list of bug fixes, see the Bug Fixes Section below.

Backwards Compatibility

It is not expected that the 2025.1.1 release would cause changes in results if upgrading from any of the prior 2025 releases, except for the specifics of the bug fixes listed below.

Bug Fixes

Domain Construction

  • Fixed a bug introduced in 2025.1.0 that could cause input grid files to not process correctly and interpret all data as being ‘no data’ values. This bug was triggered if the ‘no data’ value was a really large value (e.g. 3.40282e+38).

ESTRY

  • Fixed a bug that could cause TUFLOW to exit a simulation after a WARNING 1450 message for an arch bridge.

Outputs and Check Files

  • Fixed a bug that could create an invalid TIF output/check file if the file size was larger than 4 GB. The issue was caused by TUFLOW not correctly switching to the “Big TIFF” specification.
  • Fixed a bug with cell-centred NetCDF outputs (Map Output Format == CC) not correctly outputting groundwater results.
  • Fixed a bug that caused the ‘time’ variable in NetCDF Raster (Map Output Format == NC) to be rounded. This was especially pronounced with large output times, with values >1,000 being rounded to the nearest integer.

Other

  • Fixed an unreported bug with an internal routine within TUFLOW that compared floating point numbers. This bug most likely never caused any issues in practice, but a slightly more accurate implementation of the logic has been implemented.
