TREE-PUZZLE is a computer program to reconstruct phylogenetic trees from
molecular sequence data by maximum likelihood. It implements a fast tree search
algorithm, quartet puzzling, that allows analysis of large data sets and
automatically assigns estimations of support to each internal branch.
TREE-PUZZLE also computes pairwise maximum likelihood distances as well as
branch lengths for user specified trees. Branch lengths can be calculated under
the clock-assumption. In addition, TREE-PUZZLE offers a novel method, likelihood
mapping, to investigate the support of a hypothesized internal branch without
computing an overall tree and to visualize the phylogenetic content of a
sequence alignment. TREE-PUZZLE also conducts a number of statistical tests on
the data set (chi-square test for homogeneity of base composition, likelihood
ratio clock test, Kishino-Hasegawa test). The models of substitution provided by
TREE-PUZZLE are TN, HKY, F84, SH for nucleotides, Dayhoff, JTT, mtREV24, VT,
WAG, BLOSUM 62 for amino acids, and F81 for two-state data. Rate heterogeneity
is modeled by a discrete Gamma distribution and by allowing invariable sites.
The corresponding parameters can be inferred from the data set.

The goals of the FreeHDL project are to develop a VHDL simulator that has
a graphical waveform viewer and a source level debugger. It also aims at
VHDL-93 compliancy. The project is at a very early development stage.
This is Gmsh with support of OpenCascade.
Gmsh is an automatic 3D finite element mesh generator (primarily
Delaunay) with build-in CAD and post-processing facilities. Its primal
design goal is to provide a simple meshing tool for academic test cases
with parametric input and up to date visualization capabilities. One of
its strengths is the ability to respect a characteristic length field for
the generation of adapted meshes on lines, surfaces and volumes, and to
mix these meshes with simple structured grids.
Gmsh is built around four modules: geometry, mesh, solver and
post-processing. The specification of any input to these modules is done
either interactively using the graphical user interface or in ASCII text
files using Gmsh's own scripting language.
Impact is an explicit Finite Element Program which simulates dynamic impact
events. It has a range of elements, contact handling and different material
laws. Models can be created and viewed with external programs or the
included postprocessor.
