Gmesh Script Driven

A "languagge" to generate 1D, 2D and 3D mesh
// We can then define some additional points as well as our first
// curve.  Curves are Gmsh's second type of elementery entities, and,
// amongst curves, straight lines are the simplest. A straight line is
// defined by a list of point numbers. In the commands below, for
// example, the line 1 starts at point 1 and ends at point 2:

Point(2) = {.1, 0,  0, lc} ;
Point(3) = {.1, .3, 0, lc} ;
Point(4) = {0,  .3, 0, lc} ;

Line(1) = {1,2} ;
Line(2) = {3,2} ;
Line(3) = {3,4} ;
Line(4) = {4,1} ;

FEM Tools inside script environment

Two major environment

  • Scilab
  • Octave
  • worth noting are that they require an high level of programming skills supplying higher level of flexibilty for research
