Failed to Visualize Thermal Map

I’m trying to visualize the indoor thermal comfort surface, and I seem to have followed the steps correctly, yet am unable to obtain the results. I constantly get this very long error, please take a look at it and help me resolve this. Thank you in advance.

Your Grrasshopper file has way more components in it than is needed to recreate the issue. Next time, I recommend either simplifying your file or just uploading the log file instead of the Grasshopper definition. This file can be found at:


When I open this file, I see that your real error is the following:

Running your model through the HB Validate Model component, I see that your model is not valid and has a bunch of issues with it related to duplicated Identifiers:

Please check to make sure your model is valid before posting on the forum here.
