Cart3D v1.3 (click
here
for v1.4 or here
for v1.2 release)
 Cart3D
is a high-fidelity inviscid analysis package for conceptual and
preliminary
aerodynamic design. It allows users to perform automated CFD analysis
on
complex geometry. The package includes utilities for geometry import,
surface
modeling and intersection, mesh generation and flow simulation.
Currently
the package includes two flow simulation codes, Tiger, and flowCart.
The
package is highly automated so that geometry acquisition, and mesh
generation
can usually be performed within a matter of minutes on most modern UNIX
workstations or PC's.
The current release of Cart3D
is v1.3, (the v1.2 webdocs are
here). This release has several
major upgrades including solver improvements (flowCart), faster mesh
generation, and options for inlet/exit (power) boundary conditions.
Geometry comes
into the package
in the form of surface triangulations which can be generated from many
popular CAD packages, from legacy surface triangulations or from
structured
surface grids. Cart3D uses adaptively
refined Cartesian grids to discretize the space surrounding a
geometry
and cuts the geometry out of the set of "cut-cells" which
actually
intersect the boundary. The flow solver runs on uni- and
multi-processor
computing platforms using either OpenMP or MPI.
 What
Platforms are Supported?
Currently
supported
platforms include IRIX, Linux, SOLARIS, with limited support for Apple
OS-X. For information on other platforms, contact us.
