Unique Grid Generation. The major advantage of using AGPS for the work of grid generation or paneling lies in the fact that the surface grid generation is done in the same system as the surface geometry definition. The surface grids created with AGPS are true representations of the underlying geometry because the surface grid generation is done in the same parametric system. In the AGPS grid generation process, extracted grids (for curves, surfaces, and volumes) are exactly borrowed from parameterization maps (Subrange) of underlying geometry such that it is exactly representative of the geometry. No projection is necessary. In addition, since all parametric surface objects in AGPS are topologically rectangular patches, it is quite simple and direct to use the mesh of iso-parametric lines on any fully wetted patch to generate quadrilateral or triangular panels.

Truly Automated Grid Generation. Although truly automatic grid generation maybe something of a myth to the greater engineering community. AGPS provides solutions to creating automated computational grids that allow pre-processing on the order of seconds instead of days. Combined with the programming language and built-in packaging capability of AGPS you can have automated grid-generation tools integrated with your enterprise's trusted practices.

Easy Grid Generation.

“Grid generation should be provided with automated, accurate tools that directly link the parametric geometry model all in the same design environment. - AGPS provides this”
Since all parametric surface objects in AGPS are topologically rectangular patches, it is quite simple and direct to use the mesh of iso-parametric lines on any fully wetted patch to generate quadrilateral or triangular panels.

AGPS makes high-analysis projects like computational gridding easier and cheaper.

The subdivision of any surface into a mesh is part of its specification, and can easily be changed to control panel counts.
   
AGPS ensures that your geometry model is truly parametrically up-dateable. Compared with CAD-based curve and surface modeling, AGPS's explicit support of many entities has large advantages in modeling convenience and accuracy.

Surface Quality/Healing. While a surface may properly fit data, if that surface contains slopes, curvatures, or rates-of-curvature that violates a designer's intent, it will be a low-quality surface. Existing software attempt to "heal" CAD models through surface re-rendering which is an extremely poor method of definition, since the designer's intent is still unknown and has to be interpreted. The easy answer to surface quality is to begin with AGPS's advanced modeling constructs and algorithms. Although AGPS cannot prevent poor modeling technique and layout, it can provide more than sufficient tools to trace design intent, and highlight and fix any poorly constructed surfaces. If "surface healing" is necessary AGPS provides numerous methods to accurately fix surface flaws and extract design intent from geometry models. In fact AGPS designers at Boeing included a custom Surface Quality application that mathematically interrogates surfaces and presents visual assessments, before geometry is approved.

Does a surface have the shape that you want?
Does it have unwanted wiggles, gaps, or surfaces that do not abut properly?
Does it have a poorly parameterized layout?
All these questions should be answered and checked for quality before any paneling or surface grids are generated.


AGPS provides easy to use geometry models and libraries of analysis algorithms, for, high quality geometry creation, extraction of data, evaluation of geometry, model relationships, data exchange, visualization, and creation of scientific applications.





Interface with external processes. Another amazing feature of AGPS is it's ability to be a "mid-processor". AGPS can be used to spawn external processes with input generated within the AGPS platform. In turn, AGPS can then be used to post-processed analysis data from these processes.
