Found myself it is possible to get the saved mesh file by running gmsh from win comand promt or linux shell by

windows:
cd C:\Users\bhb\Desktop\gmsh-mit-geo
C:\Daten\gmsh-2.10.0-Windows\gmsh.exe  -3  femmesh.geo

linux:
gmsh  -3  femmesh.geo

It is possible to open a geo and with "Mesh 3;" immedately mesh the geometry. In adition I would like to save the femmesh.unv at the same process while open the femmesh.geo from gui. I could not found an option for that at the tutorials page of gmsh.

again the content of femmesh.geo:

Merge "box.step";  // some simple box
Mesh.Format = 2
Mesh.SaveAll = 1
// some line to save the unv file ?

Zitat von Bernd Hahnebach <g...@b75.ch>:

Hi gmsh users,

I have a simple geo file to mesh some step geometry. How do I save the mesh file to disk ?

bernd



Merge "box.step";

Mesh.Algorithm3D = 5;
// 1=Delaunay, 4=Frontal, 5=Frontal Delaunay, 6=Frontal Hex, 7=MMG3D, 9=R-tree
// default = 1

//Mesh  2;  // surface
Mesh  3;  // volume

Mesh.Format = 2;
// 1=msh, 2=unv, 10=automatic, 19=vrml, 27=stl, 30=mesh, 31=bdf, 32=cgns, 33=med, 40=ply2
// default = 10

Mesh.SaveAll = 1;
// Ignore Physical definitions and save all elements
