All our products are complete packages and no add-ons are required.
In fact, each of our products is a completely independent package.
Each includes
- the GUI (Graphical User Interface), which allows the user
to input data very easily within minutes,
- computational engines,
- flexible mechanisms for display of computed information,
- 3D
visualization of the platforms and computed paths, and
- an online User's
Guide.
All our products, GeomFix, DOVA and CDOVA run on
- SGI (Silicon Graphics) workstations with IRIX
operating system (IRIX is a standard
operating system on SGI workstations.)
- PC with LINUX
SGI workstations and PCs with LINUX come with standard pre-loaded software
that includes the operating system, graphics packages, etc.
Beyond these standard software, you do not need any other software
in order to run our
products and visualize models and patterns.
All our products have an integrated visualization component that is
based on excellent 3D graphics packages
(that come as a standard with
SGI systems and is available on LINUX platform)
and allow to visualize the surface model as a smooth
surface, a fireframe, a collection of vertices, etc.

DOVA and CDOVA are high-frequency packages that predict electromagnetic
fields scattered and/or diffracted by platforms.
Because each product is
based on high-frequency methods, it assumes
that the antenna is small
relative to the overall size of the platform.
_/_/_/_/_/_/ M O D E L S _/_/_/_/_/_/
- In order to run DOVA or CDOVA the user has to supply a model of the
platform.
DOVA and CDOVA uses already available CAD (Computer Aided
Design) models of platforms, such as an aircraft, or a ship.
- More specifically, DOVA and CDOVA work with 3D representation of a
platform as a flat faceted surface.
Such representations are often used for computational electromagnetic analysis,
and also are widely used for
rendering and animation, Stereolithography, VRML, Finite Element
Analysis,
design of biomedical implants, design of prosthetic devices,
planning of plastic surgery, etc.
Such models can be purchased from
various commercial vendors.
- GeomFix is a ToolBox for Fixing Geometry of Surface Models.
GeomFix enables transformation of an existing CAD model
into a model suitable or EM analysis and computations.
GeomFix also supports construction of new models based
on existing surfaces and surfaces defined by parametric
equations (for example, to create test cases).
GeomFix Toolbox includes a number of convertors from
popular CAD formats into the working format of GeomFix, DOVA and C_DOVA.
Geomfix can export the
repaired file in a number of popular formats.
Our company can also provide you with needed models for some nominal
price (depending on the complexity of the model).

The Online User Manuals describe DOVA, CDOVA, and GeomFix
and are available on the web

Training can be provided at our office in Atlanta.
Because the software
is almost completely automated, such training does not require much
time.
GeomFix
-
Training in GeomFix takes three days for
those well familiar with
platform modeling and use of CAD models in CEM/CFD
- Otherwise it is a week
DOVA or CDOVA
-
Two days of training in either DOVA or CDOVA will teach
the user how to use the package.
- In addition,
it will cover
intricacies of the software and theory behind it for
a seasoned CEM engineer
or
it will cover the introductory material for a novice.
Training is scheduled at the earliest convenience
upon completion of the purchase
and is included in the price of software (see above for details)
If the training is required at the customer's offices the price and
conditions have to be negotiated in each case.

- EVALUATION of GeomFix
Since GeomFix involves complex computations and
requires from the user competence in
the theory of geometric computations
as well as in
certain aspects of numerical analysis and computerized geometric
modeling,
it has been our policy to offer training as a part of
eveluation of our products.
- When evaluation of GeomFix is requested, the user pays for training
and receives a one month evaluation copy upon completion of the training.
- When evaluation is followed by a purchase, the cost of training
is subtracted from the cost of software.
EVALUATION of DOVA or CDOVA
Since DOVA and CDOVA involve complex computations and
requires from the user competence not only in
the theory of electromagnetic analysis but also in
certain aspects of numerical analysis and geometric
modeling,
it has been our policy to offer training as a part of
evaluation of our products.
- Training and access to DOVA and CDOVA codes are provided on our site
at a cost.
- When evaluation is followed by a purchase, the cost of training
is subtracted from the cost of software.

Maintenance includes:
Software related assistance by Email
and/or limited Telephone for 12 months
Free Upgrades for 12 months
Please note that we'll be glad to provide assistance with engineering
issues as well - on consulting basis.
In such case we will develop a
proposal (formal or informal, depending on the scope) and deliver
services upon your acceptance of our proposal.
