The Quasi-Static Electromagnetic Solvers (P-EM-QS) enable the efficient modeling of static and quasi-static EM regimes by applying the finite element method on graded voxel meshes. The solvers address the most challenging low frequency problems at the cutting edge of medical and EM compliance applications, such as simulations of EEG, MRI gradient coil fields, transcranial magnetic or current stimulation, and deep brain and spinal cord stimulator implants.
Analysis of phosphene generation by transcranial alternating current stimulation.
Each solver is optimized for a different approximation of Maxwell’s equations, offering improved speed, convergence, and accuracy for a wide range of scenarios.
Measured data and user-defined field or current distributions can be used as sources.
The P-EM-QS solvers have been validated and the uncertainties have been quantified using analytical and full-wave solutions and by comparison with measurement data. Comprehensive documentation is available for Sim4Life.
