[Gmsh] Local refinement via embedded points

[Ryan Huechteman]

Hi community,

Can someone assist me with local refinement. I had a more complex 3D
problem that didn't work so I attempted the following toy:

*lc = 1;*
*lc_fine = 0.005;*
*Point(1) = {-1.0, -1.0, 0.0, lc};*
*Point(2) = {-1.0, 1.0, 0.0, lc};*
*Point(3) = {1.0, -1.0, 0.0, lc};*
*Point(4) = {1.0, 1.0, 0.0, lc};*
*//+*
*Line(1) = {2, 4};*
*//+*
*Line(2) = {4, 3};*
*//+*
*Line(3) = {3, 1};*
*//+*
*Line(4) = {1, 2};*
*//+*
*Curve Loop(1) = {4, 1, 2, 3};*
*//+*
*Plane Surface(1) = {1};*
*Point(5) = {0.0, 0.0, 0.0, lc_fine};*
*Point{5} In Surface{1};*

which also does not work. What gives?

Thank you kindly,
Ryan
