@chris thanks. In this case I guess we need to run the HB UTCI workflow, rather than the LB UTCI workflow? In our early stage workflows, being able to avoid potentially needing to setup the HB model that has a lot more detail and inputs (soil, etc). Is it possible to have that same input in the UTC…

Ok then maybe my mindset has to be that we have two different scripts - one simple one w/ LB components, and one with HB that incorporates wind for more detailed analysis - we can work with that. Thanks for the advice as always.
