Improve default meshing strategy of solar analysis geometries

[TianjiaoYang]

Hi,

if I'm not mistaken, there was no mentioning of this mesh setting in either the instruction or the YouTube tutorial. However, I do find the granularity of the geometry meshing important. For my own exercise (see attached images), when I use U=V=2, the mesh does not reflect the geometry I designed at all. So maybe in the instruction, an additional reminder to check the mesh is necessary, because by default the mesh preview is turned off.

To Do:

• add default option in GhSolar (GHSolarObstacle?) to make uniform meshing according to grid spacing, similar to how Radiance/Daysim (and thus ClimateStudio and Honeybee) do it. So user specifies, e.g., grid spacing 0.5 m, and on a regular grid, sensor points will be added and an analysis mesh created accordingly. Additional vertices added at the mesh edges to keep the original outline of the geometry.
• keep the current meshing strategy as optional (explicit mesh input)
• needs to be done in https://github.com/christophwaibel/GH_Solar_V2
