AMR-Capable meshing software that is not based on quad/octrees
I am looking for AMR/re-meshing software (structured grids would suffice) that is NOT based on quad-octrees, i.e., a fixed refinement rate of 2 but (ideally) something user defined, i.e., ratios of 1....

Can I find sines or cosines of rational parts of π without using radians? If not, how do I reduce the errors caused solely by the transcendence of π?
this may be irrelevant for people who need fast code. But for me it's just the opposite -- i.e. in the specific situations when I know that the extra time allows me to make my calculations more ...
