Minor Release of openTELEMAC v9.1.2

We are pleased to announce the release of openTELEMAC version 9.1.2, a minor update to the 9.1 branch.

A complete list of fixes and enhancements is available on the dedicated GitLab page: 9.1.2

Key Improvements

This update includes several bug fixes and improvements aimed at enhancing the robustness, stability, and overall quality of the system.

Notable changes include:

  • TOMAWAC correction: an update has been made to the handling of SPB triad interactions to correct the directional interpolation used during energy transfers. This fix prevents excessive wave spectrum growth and improves simulation reliability in cases where nonlinear triad interactions play a significant role.

  • WAQTEL (MICROPOL) fixes in both 2D and 3D for the management of bottom sediments in the presence of dry areas, ensuring proper mass conservation and consistency between bed sediments and contaminated sediments during erosion processes.

  • Several additional bug fixes and optimizations contributing to the overall stability and reliability of the platform.
