Hi, I want to load a file that I created in OS V2.5, but my actual version is V.13.4 and when I try that I get this message: Error: Version extracted from file '2.5.0' is newer than current OpenStudio Version 1.13.4. What should I do ? Is there a way to convert it (a link or something)? Thanks
OpenStudio models are not forwards-compatible with prior versions. You will need to download and use OpenStudio version 2.5+ to open a version 2.5.0 model.
Sorry to be pedantic, but what is being discussed here is not backward compatibility, but rather forward compatibility, the ability of older software to accept inputs created by newer versions. Forward compatibility is much harder than backward compatibility and few software packages support it in a general way.
thanks for the clarification Amir - I didn't know the distinction.
If your model does not contain any features from the newer version OS, you still can open it in an earlier version by revising the version identifier to 1.13.4 in OSM file. Or you have to delete new components in your model until you can open it in the previous version. Then you can add deleted components back in the previous version. I think this not a smart way but it does the work.
OS:Version,
{52ebc7df-1931-44b8-9258-342ba3730fbd}, !- Handle
2.5.0; !- Version Identifier
You could try with this: first export the model in gbXML and then import the gbXML model to your earlier OS version, greetings
This will only import geometry, not HVAC
