Issue: The building element energy analytical model needs to be created before an energy simulation is run. This may take an extended period of time depending on the size and complexity of the model. See Energy Analysis using Building Elements - Model Validation.
Solution: Select Create the Energy Analytical Model and continue to run the energy simulation if you are ready to wait for the model to be created and want to proceed with the energy simulation.
Select Cancel to cancel the creation of the energy analytical model and the simulation request.
