CST propCST Studio Suite

SIMULA, Dassault Systèmes

CST Studio Suite is an industry-leading EM simulation tool, with multiple solvers suitable for a wide range of applications. Engineers can use these solvers to simulate antenna radiation patterns and coupling, both in isolation and as installed in realistic environments. The Hybrid Solver Task, combining FIT and MLFMM methods and the Asymptotic Solver offer an efficient way to calculate 3D propagation around large structures such as buildings and aircraft.


Model CityAltair HyperWorks

WRAP streamlines the complex task of managing valuable radio spectrum assets to provide maximum utilization and optimal performance. With support for large national and international frequency databases, WRAP's propagation models ensure comprehensive coverage across the entire radio spectrum. And with International Telecommunication Union (ITU)-compliant calculation and coordination methods, WRAP ensures compatibility with spectrum regulations while quickly identifying and resolving interference issues in remote and densely collocated scenarios (license required).
