Hello,

I am getting the following error when running energy pro v8 non residential simulation. I attempted to correct the model based on the errors messages and re run the simulation, however the simulation fails to run.

Any pointer to resolve these issues will be helpful.

below is snippet of typical error message.

Thank you, Aaron, for the feedback. Based on the errors, I checked all the space type functions and all the variables listed above, nothing appeared out of the normal. Is there a way know which spaces is causing this issue? similarly is there a way to search where "srf36812" is assigned to?

@adireddi if the EnergyPro input file is text-based, you could open the file in a text editor and search for "VentFuncType" to find the space type function and "srf36812" to find the surface. If it is not text-based, then hopefully you can export a CIBD (CBECC-Com input file) or similar energy model file that is text-based to search for these items.

To add to Aaron's advice..

EnergyPro will generate the .cibd19x (or similar) file in Documents > EnergyPro 8 > [Project Name] folder. However, default settings will delete it after the sim finishes, so you need to edit software settings to not delete "temporary files".

Once you find the file, I'd suggest opening it in CBECC-Com natively and trying to run it there. It should give you more info for troubleshooting the issue.. This may require enabling verbose error messages or other settings from within the CBECC-Com interface.
