* Numerous changes to the treatment of the default settings and values, e.g. different default viscosity formulation of default viscosity coefficients. For backward compatibility the “Defaults ==” command is available to run old models on new releases.
* Bug fixes.
Generally, there should not be substantial differences as the fundamental equations being solved are unchanged. If significant differences (>10% of depth change across the whole model) are observed then it’s most likely due to the last couple of dot points above. To identify the cause(s) for the change, the model can be run with the latest build for each release to identify in which release(s) the significant changes occurred. The changes for each release are documented in their release notes. Past releases and release notes are all available [https://www.tuflow.com/Tuflow%20Previous%20Release.aspx. here].<br>
The recommendation is usually for new or reworked models to use the newest build to take advantage of the latest features and enhancements. However, particularly if a model is calibrated, using old builds of TUFLOW or winding back default settings using “Defaults ==” is reasonable for established models.<br>
