Delcross Technologies Releases Savant V4.0

Delcross Technologies announced the Version 4.0 release of its Savant™ software for modeling the installed performance of antennas on electrically large vehicles. Among the many new features in this release are multi-bounce edge-diffraction rays that improve accuracy by modeling antenna interactions with shadowed portions of the platform, an integrated workflow with CST STUDIO SUITE® 2014 for importing full-wave antenna models for hybrid simulation, a new Scene Tree capability to enable articulated geometry assemblies and a new feature for generating parametric CAD models and platform parts.

With the introduction of Savant Version 4.0, Delcross provides the industry’s only commercial asymptotic electromagnetic (EM) analysis software to extend the Shooting and Bouncing Rays (SBR) simulation approach with Physical Theory of Diffraction (PTD), Uniform Theory of Diffraction (UTD), and Creeping Waves.

Savant simulations are configured through an intuitive and powerful graphical user interface (GUI) capable of importing and simulating complex vehicle and platform geometries that may be hundreds to thousands of wavelengths in size. Savant also leverages graphics processing unit (GPU) hardware for simulation acceleration, utilizing both scientific computing and consumer-grade NVIDIA graphics adapters. For customers using high performance computing (HPC) systems, Savant simulations can be massively accelerated through a Message Passing Interface (MPI) implementation that extracts maximum benefit from multi-core and GPU-accelerated HPC cluster architectures.

A workflow combining both full-wave and asymptotic EM analysis in hybrid simulation provides vertical RF systems integrators with accurate, efficient and error-free modeling of antenna systems integrated on large vehicles. Savant Version 4.0 introduces a seamless workflow with CST STUDIO SUITE® to import full-wave antenna modeling results from CST’s 3D full-wave time- and frequency-domain EM solvers. Imported antenna simulation data and geometry from CST STUDIO SUITE can be placed on an electrically large vehicle CAD model in Savant and used for hybrid simulation of the installed antenna performance under the influence of the actual vehicle geometry.

Several enhancements have been added to Savant’s ability to import and develop CAD models. A Scene Tree capability provides aggregation of multiple imported CAD subassemblies that can be translated or rotated. The Scene Tree can be used to define and parameterize subassembly positions like prop, rotor or engine rotations, relative spacing between vehicle geometries, or antenna placement changes. In addition, CAD subassemblies may be defined from basic parametric shapes like cylinders, cones, bricks and paraboloids, without the need to externally create and import them.
