Release Notes

Changes May 21, 2024

  • The Hysopt Platform now features improved support for named user licenses.

    • Some licenses, like Hysopt BIM Syncer, require specific assignment to users. This has been made easier and more consistent.

    • Such licenses can now be assigned to users and will then only be applicable to those users.

    • If no licenses are assigned, only non named licenses will get applied, as used to be the case

    • If licenses are assigned, they take precedence over automatically applied licenses, so then all required licenses should be assigned.

    • If multiple licenses are assigned (max 1 of each type), the user will receive the combination of features from all assigned licenses

    • Steps have been taken to ensure that existing license behavior is respected

Changes Feb 27, 2024

  • A new cost component “Carbon emissions tax” is available for the Pareto Analysis

  • The Admin Portal is undergoing changes to improve support for user bound licenses, like the BIM Syncer.

    • As such the User edit screens are extended with a License Assignments section.

    • This will enable assignment of licenses to individual users, potentially differentiating which features are available to which users.

    • This is a preparation step. There is no enforcement YET of the selections made here. This will come in an upcoming release.

      • Hence, no changes are required and license assignment will be handled automatically

      • Expect the BIM Syncer license assignment to be integrated into this screen in an upcoming release.

  • New "Polyvalent four-pipe heat pump" base circuit has been added to both the heating and cooling libraries. The polyvalent four-pipe heat pump is a heat-pump based production unit that can deliver simultaneous heating and cooling, independent heating and independent cooling all in one system.

Changes Sep 26, 2023

  • Some models created between Sep 12, 2023 and Sep 26, 2023 , might have a deprecated diversity standard (based on DIN1988-300 v1) defined by default.
    If that's the case for your model, the diversity standard will be automatically upgraded to the newer version (based on DIN1988-300 v2) when you open it again. This might influence (improve) your diversity calculations a bit.

  • Simulation results are no longer lost on any save. They are retained until a change is made that could potentially influence the results.

    • E.g. Adding labels, moving BCs, ... should no longer lead to loss of simulation results

    • E.g. Changing a parameter, pipe length, model settings... will still lead to loss of simulation results on save as they constitute changes that will affect simulation results.

  • Introduction of multiple x-axes in graphs: we display multiple x-axes for the use cases where different series with different x-axis units get shown together.
