LEDAS has released version 0.5b of its Variational Geometric Solver solution (LGS)

LEDAS has released version 0.5b of its Variational Geometric Solver solution (LGS).

This release is a part of LGS Early Access Program conducted by LEDAS since April 2003.

An improved version will be available for the EAP participants only. User-defined curves support including tangency and incidence constraints was added to the 0.4b version. Equal Radius constraint support was added for circles. A number of improvements resulted in increasing of stability and performance of LGS.

LEDAS has released version 0.4b of its Variational Geometric Solver solution (LGS)

LEDAS has released version 0.4b of its Variational Geometric Solver solution (LGS).

This release is a part of LGS Early Access Program conducted by LEDAS since April 2003.

So new, greatly improved version will be available for EAP participants only. Ellipse object, some vital constraints and features were added to the 0.3b version, resulting in comprehensive functionality of a generic geometric solver. Number of improvements made increasing stability and performance of LGS.

The 4th anniversary of LEDAS cooperation with Dassault Systemes (France) - a worldwide leading software developer of product lifecycle management (PLM) solutions.

The 4th anniversary of LEDAS cooperation with Dassault Systemes (France) - a worldwide leading software developer of product lifecycle management (PLM) solutions.

On June 22, 1999 LEDAS Ltd. and Dassault Systemes (DS) signed a Cooperation Agreement based on the previous three years of cooperation history between DS and the Russian Research Institute of Artificial Intelligence.

The cooperation between two companies is organized as a series of contracts (supplements) aimed at integrating the LEDAS solutions into CATIA Version 5 software. The supplements included development and maintenance of a powerful mathematical constraint solver, implementing end-user solutions based on this solver, extension of the user shells functionality according to the needs of DS customers, and research projects intended to prepare future constraint-based industrial solutions. Since 1999, in the framework of the Cooperation Agreement, 11 contracts have been successfully fulfilled.

One of the solutions developed by LEDAS for CATIA Version 5 was issued with V5R8 release of the system and integrated into CATIA Knowledge Advisor - to enhance this CATIA product, which allows users to embed knowledge into designs and leverage it to maximize productivity of engineering decisions by design automation and reducing human errors. When designing a product with CATIA Version 5, a user comes across a system of mathematical equations to be solved. Whatever these equations (linear or not) are, CATIA provides user with a resolution method - a "SetOfEquations" capability accessed through the Knowledge Advisor workbench. It is based on original mathematical solver developed and maintained by the LEDAS programmers.

Another end-user solution developed by LEDAS, called Constraint Satisfaction, was integrated into the CATIA Product Engineering Optimizer and issued with V5R10 release. Its key advantage is to solve not only pure mathematical functions, but also CATIA measures and other black-box functions for mathematical solver. Solving capabilities are provided with new constraint satisfaction algorithms - know-how developed by the LEDAS mathematicians.

As a private company with its proprietary technologies, solutions, experience, and a high-skilled team, LEDAS is open and ready to cooperate with all partners that need modern constraint-based technologies to add new value to their solutions.

LEDAS launched The Early Access Program The Ledas Geometric Solver.

LEDAS launched The Early Access Program The Ledas Geometric Solver. A broad range of potential customers (including major CAD development companies) are invited to join this program. The program is also open for everybody - an individual or a company - who considers the possibility to use 2D geometric constraint solver in his/her software products.

The market advantages of the Ledas LGS solution are characterized at The Ledas Geometric Solver homepage.
