      Cart3D v1.3  (click here for v1.2 release)

What is Cart3D?  click here to see more examples
click on "Images" for more examplesCart3D 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?
