8.2 Non-interactive mode

Gmsh's second operating mode is the non-interactive (or `batch') mode. In this mode, there is no graphical user interface, and all operations are performed without any user interaction(8). For example, to mesh the first tutorial in non-interactive mode, just type:

> gmsh t1.geo -2

To mesh the same example, but with the background mesh available in the file ‘bgmesh.pos’, type:

> gmsh t1.geo -2 -bgm bgmesh.pos
