|
|
been drastically improved for all geometrical transformations, and most notably
|
|
for extrusion). As a consequence, the internal numbering of geometrical entities
|
|
has changed: this will cause incompatibilities with old .geo files, and will
|
|
require a partial rewrite of your old .geo files if these files made use of
|
|
geometrical transformations. The syntax of the .geo file has also been
|
|
clarified. Many additions for scripting purposes. New extrusion mesh
|
|
generator. Preliminary version of the coupling between extruded and Delaunay
|
|
meshes. New option and procedural database. All interactive operations can be

|
example. Many stability enhancements in the 2D and 3D mesh
|
|
algorithms. Performance boost of the 3D algorithm. Gmsh is still slow, but the
|
|
performance becomes acceptable. An average 1000 tetrahedra/second is obtained on

a 600Mhz computer for a mesh of one million tetrahedra. New anisotropic 2D mesh
|
|
algorithm. New (ASCII and binary) post-processing file format and clarified mesh
|
|
file format. New handling for interactive rotations (trackball mode). New
|
|
didactic interactive mesh construction (watch the Delaunay algorithm in real
|
|
time on complex geometries: that's exciting ;-). And many, many bug fixes and

|
cleanups.

|
|
plane surfaces; added example 13.
