General Notes

This is a patch release for TUFLOW 2025.0. This release fixes several bugs in ESTRY, including a memory allocation error for models with over 50,000 channels, and an issue with anomalous concentrations occurring downstream of channels in models using the advection-dispersion (AD) functionality. For more details and a list of other fixes, see the Bug Fixes Section below.

Backwards Compatibility

It is not expected that the 2025.0.3 release would cause changes in results if upgrading from any of the prior 2025.0 releases, except for the specifics of the bug fixes listed below.

Bug Fixes

ESTRY

  • Fixed a bug with memory allocation that could caused a should not be here error in ESTRY models with more than 50,000 channels.
  • Fixed a bug which could cause WARNING 2073 to be spuriously reported when using a 1d_pit layer in conjunction with the Pit Search Distance command.
  • Fixed a bug with tracer concentrations when using the 1D advection-dispersion (AD) functionality. This bug caused the simulated concentration to diverge in long pipes (>1km) with gradually changing flow. For most urban drainage applications, that have shorter 1D pipe sections and rapidly changing flow, the impact of this fix is marginal.
