This occurs if the OpenStudio application cannot locate the EnergyPlus executable. Ensure that EnergyPlus 9.2.0 is installed in its default root directory ( C:\EnergyPlusV9-2-0 on Windows). Within the OpenStudio Application, navigate to Preferences -> Forgivable Directories and manually path the executable if necessary. 2. Ruby Script/Measure Failures

While the official release notes for version 2.9.0 highlight several new features including missing methods added to the model API, performance improvements, and bug fixes, version 2.9.1 builds upon this foundation with refinements and stability enhancements. The most significant features of this version include:

OpenStudio 2.9.1 is hard-coded to compile and run with EnergyPlus 9.2.0 .

The requirement for SketchUp Make 2017 creates significant constraints. This version of SketchUp is no longer available for download from the official SketchUp website, and newer versions of SketchUp are not compatible with OpenStudio 2.9.1's plugin. Users who did not preserve an installer for SketchUp Make 2017 may find themselves unable to use the plugin integration. openstudio 2.9.1

Check the run folder inside your project directory. Open the eplusout.err file using a text editor. This file contains the raw text logs from EnergyPlus detailing whether the crash was caused by severe geometric self-intersections or unlinked HVAC nodes.
