ADAPTIVE RESEARCH INTRODUCES CFD2000/STORM SOFTWARE PROVIDING INTEGRATED
ENVIRONMENT FOR COMPUTATIONAL FLUID DYNAMICS

(Huntsville, Alabama -- December 14, 1993) Adaptive Research today
announced the release of its CFD2000/Storm version 2.0 computational fluid
dynamics (CFD) software which provides a completely integrated environment
for the modeling and analysis of fluid flow and heat transfer phenomena.
From the intuitive, window environment the user can define their geometry,
generate structured computational grids, apply boundary conditions,
specify fluid and material properties, monitor and control the solution
procedure and manipulate flow visualization graphics. 

Four main modules comprise the CFD2000 package. The central graphical user
interface (GUI) manages all data files during the model preparation
analysis cycle, provides for Cartesian and Cylindrical Polar grid creation
and directs the application of boundary conditions, material properties
and solution and output control. The EasyMesh-3D module enables the
creation of complex geometric domains and the generation of structured
grids in body-fitted coordinates. The Storm finite-volume flowfield solver
performs the integration of the flowfield physics on the resulting
numerical grid. Each of these modules runs directly from the menu-driven
graphical user environment which greatly reduces the amount of training
required to use the program and also facilitates its use by occasional
users. State-of-the-art scientific visualization software is provided to
maximize interpretation of computational results.

The CFD2000 package includes whole-field 3D solvers which operate on the
entire domain simultaneously thus enhancing convergence speed and
requiring far fewer iterations than conventional slab-wise solvers. The
solver has been designed to take advantage of vector and
parallel-processing techniques. The program also uses a non-staggered
(collocated) grid which stores all velocity components and scalar
quantities in the center of the cell. This avoids excessive averaging in
body- fitted coordinates and thus improves the accuracy of the solution
and the stability of the code as well as reducing storage requirements.
The user is provided a choice of convection term formulations including
second- and third-order accurate schemes.

The CFD2000 program also provides Grid Sequencing methodology that
automates what is often the most time-consuming portion of CFD. During the
analysis the grid may be refined (or coarsened) enabling a final-grid
solution to be rapidly obtained starting from a coarse grid, without
stopping the analysis. This feature replaces having to manually redefine
the mesh, interpolate the flowfield solution, and restart the analysis.

Another time saving feature of CFD2000 is the way it simplifies the process
of code customization. This feature is frequently required because it is
impossible to anticipate every physical phenomenon or specialized fluid
properties formula a priori. The key is that the user modifiable code is
broken down into structured FORTRAN subroutines, each of which has a
clearly defined function and can be easily modified when necessary. One
line formulae can be entered from the GUI menus and the FORTRAN is
automatically created by the GUI for the user.
