ere are ways to remap the data (PathMapper etc) and there's an excellent tutorial by David Rutten about path mapper on this forum somewhere.
And always look at whether you simply need to flatten your data to ba able to work with it.
For point lists I often use the PointNumber component to help visualise the data and the good old Panel component helps too!
When you see some of the elegant, compact definitions on here, there often seems to be some mystical foresight needed right from the first component but hopefully this jedi skill comes with practice!…

windows. I manage to have proper HBZones with RADMaterials and EPConstructions (I've run Daylight calculation on them successfully), but when I plug the zones to GrizzlyBear this error appears:
Solution exception:'EPZone' object has no attribute 'getCurrentLoads'
In addition, something similar happens when I plug these HBZones to the newest decomposeByType component, althought it works properly when plugged to the previous version of it. This is what the error says:
Solution exception:'hb_EPZoneSurface' object has no attribute 'BC'
Same thing with SetEPZoneConstruction:
Solution exception:'hb_EPZoneSurface' object has no attribute 'BCObject'
Any thought?

st for the quality of the mesh.
Actually, convergence is much more than simply having low residuals. You can have a wrong solution with very low residuals. Usually, it is a combined process of both run time information on residuals and having an idea or expectation of what the simulation results should be. Another way of assessing convergence is if the residual values have been stable (within a very small limit, e.g. 1E-5) for more than a certain number of iterations (e.g. 1000). We are planning to provide run-time residual plots in Butterfly, hopefully soon. These plots can help keeping an eye on the solution.
You could try as a test if you want to switch to a blend of first and second order (by swapping upwind with linearUpwind in the fvSchemes)
.
Concerning mesh quality there are a number of ways, some of which are a bit advanced for this post and for BF's current capabilities. The best way to start is by refining the background mesh (i.e. the blockMesh). You can do that by assigning more cells to the x, y and z directions in the blockMesh component. However, make sure you increase the max global cells. I would suggest you monitor the output of the blockMesh in order to know the total number of cells there. Your max global cells has to be higher than that for SHM to even work. I'd suggest 2x to start with. Ofc all that requires a bit of trial and error depending on the case at hand.
Hope this helps!
Kind regards,
