Hello all,
I am trying to mesh a cube surface with second order triangles. The
first order mesh is fine, but the second order hangs. I am using the
downloaded Linux binary of gmsh 2.4.2 and my input geometry is:
lc = 1.0 ;
Point(1) = {-1,-1,-1,lc} ;
Point(2) = { 1,-1,-1,lc} ;
Point(3) = { 1, 1,-1,lc} ;
Point(4) = {-1, 1,-1,lc} ;
Point(5) = {-1,-1, 1,lc} ;
Point(6) = { 1,-1, 1,lc} ;
Point(7) = { 1, 1, 1,lc} ;
Point(8) = {-1, 1, 1,lc} ;
Line(1) = {4, 8};
Line(2) = {8, 7};
Line(3) = {7, 3};
Line(4) = {3, 4};
*********************
Line(5) = {1, 1}; *
Line(6) = {1, 1}; *

Hi Michael,
you have two zero length line here !
Regards,
Dave
