Dear Enrico:
I find fastercap code have "Automatic mesh refinement".
1. do you have code mesh refine reference material?
2. RefineCriteria() principle is what.

Dear Yan,

you can check the FasterCap referenced papers at ht*ps://w* (replace the * with the proper letters in the address, this is an anti-spam measure), in particular the papers from Appel, the one from Hanrahan, and the one by Weiping Shi.
In a nutshell, the mesh refinement is based on Appel's algorithm that ws originally devised from the N-body problem (just like the multipole algorithm used in FastCap was invented to accelerate N-body computations) and then extended to solve Radiosity problems by Hanrahan.
FasterCap uses the same algorithm as used for Radiosity in a similar fashion to what done by Weiping Shi - although I personally find this latter paper a bit confusing.

Best Regards,
