Hi Chris, I am currently looking into the same comparison for the UTCI calculation between the legacy and new LB. I would like to understand the difference in the MRT results between the two versions that is significant. Both simulations match time-step. SolAdjustMRT_Legacy_vs_New1.3_V2.gh (848.3 KB)
This would lead to quite different results between versions. In the image is the average UTCI when the sun is up.
