Hello,
I am wondering about one step of the 2-D mesh process within Gmsh.
Actually, I would like to know how the "mean plane" is defined in the
case where all the points of a 'plane surface' are not really in a
same plane.
In the source code, I found that the resulting plane is defined
according to a least squares criterion; but which form of the criterion
is it about? In other words, which expression is minimized?
I am using this option to approximate (slightly) non-planar faces by
planar ones...
I thank you in advance for your answer (in fact, it is for a
presentation next week),... and thank you for Gmsh too!
Yours sincerely,
--
