Also in this release: results as textual labels and captions in the model viewer, element and node annotations, element groups shown as colours, plot export to HTML, templates in the components database, the tank element extended with liquid surface pressure and nozzle height, and support for the 2023 edition of ASME B31J.  Dynaflow Research Group, 2026 [mailto:info@dynaflow.com](mailto:info@dynaflow.com)
