MultiLoop III - Features

MultiLoop III is a comprehensive electromagnetic simulation software package for accurately modelling the quasi-static response of bent and welded thin sheets in free-space. The sheets can be penetrated by holes and can have a variable surface resistance. At the heart of the solution is a multi-threaded proprietary time-stepping solver coupled with a geometrical optimizer that parses the mesh. See MultiLoop III Tutorials.

Almost any geometry can be modelled, including multiple sheets, bent sheets, welded sheets, sheets with holes, close shells and combinations of the above. Scattering is calculated using MultiLoop III, with shapes being formed with the companion program, Pebble. The code is multithreaded and very fast. Numerous tests have validated the accuracy of the solution.

Summary of MultiLoop's Capabilities
  • Mesh Sizes: 8000+ nodes on a quad-processor desktop / 3000+ node on a laptop
  • Waveform: Any - full flexibility
  • Gates: Any - full flexibility
  • System Geometry: Flexible - Loops, dipoles, constant source fields, combinations of these; moving and fixed sources
  • Mesh Geometry: Thin sheets, bounded or pseudo-infinite
    • Sheets - Planar or curved; variable surface resistance
    • Shells - Volumes can be enclosed by the mesh
    • Welded Junctions - galvanic current flow between contacting sheets
    • Holes - branch cuts are automatically placed to satisfy Faraday's Law in the hole
    • Resistance - Variable surface resistance can be applied to the mesh
    • Import - Meshes can be imported from an ASCII file
  • Scripts: A flexible scripting language can semi-automate may routine tasks
