Vector Fields announced an electromagnetic design tool for coaxial devices such as connectors and attenuators. By providing two-dimensional electromagnetic simulation only, said the company, the new tool eliminates fundamental barriers that have held back the adoption of CAE in this sector: the very high cost of conventional 3D electromagnetic software, and the long simulation times involved.

Called Concerto AS, the new software package is a variant of Vector Fields' new high frequency Concerto toolsuite. It will simulate a coaxial RF connector in a few seconds, and costs around Rs.2.27 lakh ($5,000) per seat.

According to Vector Fields, the 2D simulation is used in a way that does not impose restrictions on users. Concerto AS accepts 3D drawings imported from CAD packages, and also comes with its own 3D geometric modelling tool. Once the 3D component design is available, the software takes an axisymmetric slice out of the design, for analysis by the 2D Finite Difference Time Domain electromagnetic solver. This approach maintains compatibility with the full capabilities of 3D electromagnetic simulation software, allowing users to upgrade at any point in the future as the benefits of CAE are realised.

Tools for adaptive solutions and model parameterisation are included in the software. An adaptive solver is also included in Concerto AS which can automatically refine the mesh size used on the model of the connector component, to reach a user's target accuracy of solution.

Upgrade options include the addition of an optimiser tool, which will automatically find the best solution for multiple parameters, and upgrade to the full 3D Concerto package.

The new Concerto AS tool is available immediately and cost around Rs.2.27 lakh ($5,000)/seat.
