Concerto v7 software for high-frequency electromagnetic design presents improvements that accelerate simulation speed. These advances include 64-bit PC processing support, better distributed processing of simulations, improved support for exploiting periodicity in designs, and a tool that intelligently applies multiple algorithms to resolve complex problems.
The v7 version has a 2D or 3D design-simulate-analyze-optimize tool-chain for high-frequency electromagnetic applications. You can create component or system models through the integrated geometric modeler, or import them from CAD programs. CAD formats supported include CATIA, ProEngineer, IGES. SAT and STEP.
As standard, Concerto offers a Finite Difference Time Domain (FDTD) simulator. Depending on the application, you can add two additional simulation options. A Method of Moments (MoM) tool simulates large environment problems such as installed antenna performance. A Finite Element Method (FEM) tool performs eigenvalue analysis that can be used to characterize microwave resonator and cavity designs.
Applications span the high frequency spectrum and include antennas, waveguides, cavities and resonators, filters, connectors, microwave heating, and radar systems and signatures.
The previous 32-bit version of Concerto could run models with as many as 20 million cells on a 3 Gb PC. The new 64-bit version removes the memory constraint on model size. This feature is helpful for antenna designs that must account for the effect of external structures on performance, such as the human head and hand. An accurate simulation of a horn antenna 10 wavelengths long, with an aperture of six wavelengths, takes less than five minutes on a modest single-processor laptop.
Several processors divide a problem and execute it in parallel. The execution speed is aided by multi-threaded code rewritten using the OpenMP standard for shared memory programming.
The package’s previous one-dimensional support, which was used for applications such as simulating waveguides and filters with repeated geometry, has been extended to 3D. This change increases flexibility, speeding the simulation of antenna arrays, meta-materials, and other systems.
An automatic optimization tool for the MoM and FEM solvers makes it possible to handle multiple variables and multiple goals, even if you specify competing objectives. It first runs a primary series of simulations across the design space to provide a basis for understanding where the likely solution lies, before homing in on the best fit. The new tool complements the existing optimizer for the FDTD solver.
