ELF SOLUTION
The SEMCAD X Matterhorn ELF Solution comprises a family of quasi-static solvers for modeling extremely low frequency (ELF) and static applications, and movements in static fields. The novel implementation of electro and magnetic static and quasi-static approximations of Maxwell’s equation on a rectangular grid significantly extends the performance of SEMCAD X Matterhorn. Seamless integration into our highly advanced user-friendly GUI supports expanded applications in highly complex structures.
Streamlined workflows are available in SEMCAD X Matterhorn in the form of specific toolsets and features. The finite element method (FEM) and finite-difference time-domain (FDTD) solvers within the solution are optimized for different approximations of Maxwell’s equations, offering improved speed and accuracy for a wide range of scenarios.
Measured data and user-defined field or current distributions can be used as sources.
The quasi-static solvers have been validated, and the uncertainties have been quantified with analytical and full-wave solutions and by comparison with measurement data. Comprehensive documentation is available for SEMCAD X Matterhorn.
