[Gmsh] coarsening existing mesh from other mesher,

[Mikhail Artemiev]

Hi!

You can work with your triangulation in gmsh, converting mesh file to one of 
the appropriate gmsh file formats.
For instance, .msh file can be something like this

$MeshFormat
2 0 8
$EndMeshFormat
$Nodes
number of #pts
1 x1 y1 0
2 x2 y2 0
....
$EndNodes
$Elements
number of elements in your section #connectivity
1 2 3 1001 1 0 1 3 5
2 2 3 1001 1 0 3 8 9
...
$EndElements

You can find the description of the .msh file format in the manual.
