What is the default unit in GMSH
What is the default unit that is used by the gmsh (i.e. mm or m)? I couldn't find any information about this. I need to produce a volumetric mesh where cube is inside of another cube, but in mm scale. I have wrote a .geo file as below.
SetFactory("OpenCASCADE");
Box(1) = {-30, -30, -30, 60, 60, 60};
Box(2) = {-15, -15, -15, 30, 30, 30};
Physical Volume("box") = {2};
v() = BooleanFragments{ Volume{1}; Delete; }{ Volume{2}; Delete; };
Physical Volume("whole") = v(#v()-1);
I have got the point coordinates as below. But what is the default unit here ?
array([[-15. , -15. , 15. ], [-15. , -15. , -15. ], [-15. , 15. , 15. ], ..., [ 21.85311819, 2.30699305, 23.23494686], [-24.42671837, -24.84379249, 24.67779984], [ 24.84507831, 22.99210772, 24.65952139]])
