I have been in love with the new GPU-based PixelCounting Shading Calculation Method that was added to EnergyPlus in version 9.3. It has brought about a Renaissance in my use of FullInteriorAndExteriorWithReflections for solar distribution.
I have noticed that using PixelCounting gets rid of the CHKBKS error noted in this issue. However, I still get the following warning when running certain types of models with PixelCounting:
** Severe ** DetermineShadowingCombinations: There are X surfaces which are casting surfaces and are non-convex
From the documentation in the EnergyPlus Input/Output reference that I linked to, it seems that using PixelCounting should eliminate the negative effects of this Severe error. So I was wondering if I can just ignore this sever error whenever I use PixelCounting.
If anyone wants to recreate the error that I am talking about, here is a sample IDF with PixelCounting that returns the Severe warning in the .err file:
