Description
|
|
Refine by splitting all three edges of triangle ('red' refinement).
|
|
Neighbouring triangles (which are not marked for refinement get split
|
|
in half ('green') refinement. (R. Verfuerth, "A review of a posteriori
|
|
error estimation and adaptive mesh refinement techniques",
|
|
Wiley-Teubner, 1996)
