    CST Studio Suite

    CST Studio Suite

    Dassault Systèmes

    CST Studio Suite is a high-performance 3D EM analysis software package for designing, analyzing, and optimizing electromagnetic components and systems. Electromagnetic field solvers for applications across the EM spectrum are contained within a single user interface in CST Studio Suite. The solvers can be coupled to perform hybrid simulations, giving engineers the flexibility to analyze whole systems made up of multiple components in an efficient and straightforward way. Co-design with other SIMULIA products allows EM simulation to be integrated into the design flow and drives the development process from the earliest stages. Common subjects of EM analysis include the performance and efficiency of antennas and filters, electromagnetic compatibility and interference, exposure of the human body to EM fields, electro-mechanical effects in motors and generators, and thermal effects in high-power devices.
