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.
