The Electromagnetics Full Wave Solvers (P-EM-FDTD) enable accelerated full-wave, large-scale EM modeling (> billion voxels) with Yee discretization on geometrically adaptive, inhomogeneous, rectilinear meshes with conformal sub-cell correction and thin layer models, with support for dispersive materials. The solver includes a unique adaptive subgridding algorithm (from Acceleware) that facilitates the highest possible effectiveness in local mesh refinement.

Optimal simulation speed is achieved with native Graphics Processing Unit (GPU) and MPI accelerations, which were developed by our team who first introduced EM accelerated solvers together with Acceleware in 2006.

The unique bidirectional Huygens box approach overcomes the difficulties associated with models that extend across multiple scales and require widely varying resolutions.

These solvers, the most frequently applied of their kind in near-field dosimetry, have been have been extensively validated and documented according to the IEEE/IEC 62704-1 standard as well as by comparisons with measured data (> 200 publications). Comprehensive documentation is available for Sim4Life.
