Purpose:
Demonstrates how to generate a tet mesh:
('ng_vol' from the netgen pakage must be available)

either use the vda2fbd converter or use the available fbd file
(vda2fbd halter.vda > halter.fbd)
or use the cad2fbd converter for the conversion of the step or iges files

use -a for automatic mode:
cgx -a halter.fbd

# generate and export a tet mesh, type:
body ! all
elty all te10
mesh all
send all abq

# or do first a surface meshing with manipulations and separate tet-meshing:
elty all
elty all tr6u
mesh all
(optionally use 'qmsh' for mesh-adjustments)
mesh all tet
(optionally use 'mesh all tet 4.' were '4.' is the target-size for the tet-
 elements)
