Solver - Fast and powerful XPU technology

Powerful XPU technology The XPU technology is an IMST invented software acceleration technique for efficient EM simulation. Adaptive just in time code compilation, individually optimized for the CPU and simulation model, ensures best performance. High simulation speed is guaranteed due to full parallel computation on modern PCs and workstations (faster than other FDTD codes on GPU supercomputers). Efficient caching of FDTD coefficient saves up to 50 % memory. XPU technology enables accurate full 3D EM design of larger and more complex structures compared to regular FDTD and FEM based EM simulation tools.

Single and Cluster Simulation
Single and Cluster Simulation

EMPIRE XPU features the fastest FDTD solver on market. Its unique XPU algorithm is a software driven acceleration which runs multiple time steps in the last level caches before exchanging and reassemble data with the main memory.

  • Powerful XPU technology
  • Parallel simulation is supported on multiple cores and CPUs
  • Remote simulation capabilities
  • Cloud simulation support (Amazon AWS and Microsoft Azure)
  • Cluster Solver
  • Multi port processing
  • Thermal Solver
Variable Sweeps and Optimization
Variable Sweeps and Optimization

Geometrical and physical properties can be parameterized and automatically varied for tolerance, yield analysis or optimization. If available, jobs can be distributed on remote hosts in a network. Each sweep or optimization step creates unique folders for tracking the result.

  • Variable range, lists or equations
  • Complete result folders for each variable combination
  • Collection of different optimizer (Gradient, Simplex, Newton, Derivative-free, Random, …)
    • Range (e.g. frequencies, angles) or single value goals (e.g. efficiency)
    • Multiple weighted goals
  • Distributed or sequential execution
Far Field Processing
Far Field Processing

Far fields are obtained by recording the near field on a Huygens surface (simulation boundary) and applying a far field transformation during post-processing. This allows a compact simulation domain which is only a little larger than the radiation source itself.

  • Multi-frequency or broadband recording
  • Arbitrary far field cut angles or 3D radiation patterns
  • Directivity, Gain, Total gain or electric field normalization
  • MIMO envelope correlation coefficient calculation
  • RCS (mono-static) or bi-static scattering cross section analysis
Near Field Processing & SAR
Near Field Processing & SAR

For analyzing fields in human bodies several averaging methods are defined in compliance standards. A low frequency algorithm can be applied in case of very low frequencies, e.g. coil charging.

  • Specific Absorption Rate (SAR) with mass averaging methods
  • Averaged Current Density (ACD) with area averaging
  • Averaged internal electric field (EIAV) with volume averaging
  • Averaged power density (PD) with area averaging
