node-gmsh

Node.js binding for Gmsh.

Basic Usage

node-gmsh provides a chain API which is inspired by gm.

var gmsh = require('gmsh');
var t1 = [
    'lc = 2.5e-2;',
    'Point(1) = {0, 0, 0, lc};',
    '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} ;',
    'Line Loop(5) = {4,1,-2,3} ;',
    'Plane Surface(6) = {5} ;',
    'Physical Point(1) = {1,2} ;',
    'MyLine = 99;',
    'Physical Line(MyLine) = {1,2,4} ;',
    'Physical Surface("My fancy surface label") = {6} ;',
    'Field[1] = Box;',
    'Recombine Surface {6};'
].join('\n');

gmsh(t1, 'geo')
    .dimension(3)
    .write('/path/to/t1.msh', function(err){
        if (!err) console.log('done');
    });
