HYPERSIM 2025.2.1 - minor update

I/O Interfaces

OPAL-RT Board

• Fixed simulation crash when I/O interface was configured to be the hardware synchronization source of the model and it was using an external synchronization source (master with external clock mode).

• Fixed loss of connections made with a remote’s data points when its name was changed.

Synchronization

• Fixed Oregano card initialization in 1PPS and IRIG-B modes.

HYPERSIM 2025.2.0 - initial release

Software Toolboxes Installed with HYPERSIM

New features

• A new preference has been introduced to enforce strict version matching between the host and target when starting a simulation. This check is enabled by default, ensuring that simulations will now fail to start if the target is running a different HYPERSIM version than the host, helping to prevent potential incompatibility issues.

• The Data Logger API now supports Python versions 3.11, 3.12, and 3.13.

Improvements

• Users can now open and edit models in HYPERSIM even if the host license has 0 cores enabled. Simulation remains unavailable, but model editing is now accessible.

• When attempting to update a UCM using an unchanged definition file, the warning popup now includes a "Force Update" button. This allows users to proceed with the update even when no changes are detected.

• The free space validation before installing HYPERSIM now accounts for external tools installed alongside the software.

• The Python API function displayDevice now shows expressions on attributes.

• The https://opal-rt.atlassian.net/wiki/pages/createpage.action?spaceKey=pdochs&title=ScopeView%20%7C%20Templates&linkCreation=true&fromPageId=1387921479 now includes documentation for the “Save using relative path” option, which allows templates to reference recordings located next to the model using relative paths.

• Rework the https://opal-rt.atlassian.net/wiki/spaces/PDOCHS/pages/149947197 model in HYPERSIM for consistent Loadflow results.

• The https://opal-rt.atlassian.net/wiki/spaces/PDOCHS/pages/1150812780 has received many improvements:

  • Multicore support for real-time simulation. New ePHASORSIM Interface parameters allows the user to specify a desired number core for parallel computation done in the solver. The system choses which core to assign.

  • I/Os are now exposed as bundles.

    1. The https://opal-rt.atlassian.net/wiki/spaces/PDOCHS/pages/1150845258 model was updated to benefit from bundles.

  • Improved UI/UX for displaying errors, block creation field validation and user feedback

  • ePHASORSIM logs can be now found in %USERPROFILE%/HYPERSIM/log

Bug fixes

• Fixed an issue where the https://opal-rt.atlassian.net/wiki/spaces/PDOCHS/pages/150079941 component was not getting updated when edited after Analyze.

• Fixed the https://opal-rt.atlassian.net/wiki/spaces/PDOCHS/pages/149719120 component to correctly disable code changes during simulation.

• Fixed an issue where the wrong eFPGASIM version was used after installing a different HYPERSIM/RTLAB version.

• Fixed help buttons that were not working correctly when linked to documentation pages containing special characters.

• Fixed an issue with https://opal-rt.atlassian.net/wiki/spaces/PDOCHS/pages/149523072 connections to the FPGA when the input/output name in Schematic editor contained forbidden characters in HYPERSIM schematic, such as white spaces.

• Fixed dashboards compatibility on hosts running Windows Server.

• Fixed an issue where eFPGASIM models containing signal names with special characters (e.g., spaces) could cause errors.

• Fixed an issue where parameters of an UCM were not validated during Analyze.

• Fixed a crash during Analyse with imported PSCAD models having components with long name.

• Fixed an issue where updating some parameters on lines and cables during a simulation could cause unexpected errors on the target.
