Thank you for reporting this issue, @gonchotorena . It seems this is a bug that was introduced when we upgraded to EnergyPlus 9.6 and the InternalMass object got a new field for “Space Name” now that EnergyPlus supports spaces as well as Zones. I just pushed a fix to the latest development version of the plugin:
You can get the fix on your end with the “LB Versioner” in an hour or so.
No. Just run the LB Versioner component and restart Rhino. That will updated your installed components and core libraries to the latest development version of the LBT Grasshopper plugin. Afterwards, you may need to run the LB Sync Grasshopper File component on your old Grasshopper definitions in order to sync the components on the canvas with the version that you have installed.
