V-Lox

V-Lox is a high performance computational electromagnetics simulation tool incorporating the latest advances in hardware and algorithmic acceleration techniques.  V-Lox uses a rigorous formulation based on the Method of Moments to ensure accurate and efficient solutions to antenna, scattering, and microwave circuit problems.  With the ability to handle geometries composed of arbitrary metallic and material (dielectric and magnetic) objects, V-Lox is ideally suited to handle all of your advanced modeling requirements.

New in Version 2.2!

V-Lox Version 2.2 released in November 2016.  New features and improvements include:

  • New matrix compression algorithms improve runtime performance by up to 6X
  • New support for GPU-accelerated direct solver
  • Support for latest generation NVIDIA GPUs
  • Improved method for solving problems involving materials with frequency-dependent properties

With of the latest version of V-Lox you can not only solve larger problems faster but also solve problems not previously thought possible. V-Lox can now solve problems in minutes or hours that took days or weeks even only a year ago.  We recently demonstrated accurate solution of a problem with 1 million unknowns in only 8 hours on a single workstation.

Application Areas

Antennas

V-Lox provides users with the ability to model complex antenna types:

Focusing Lens

  • Wire antennas
  • Microstrip antennas
  • Aperture antennas
  • Slot antennas
  • Horn antennas
  • Wideband antennas
  • Conformal antennas
  • Embedded antennas
  • Fabric antennas
  • Lens antennas
  • And many more…

V-Lox also supports antenna placement analysis.  Using V-Lox’s fast direct solver, users are able to explore numerous antenna positions and orientations while minimizing total runtime and maximizing solution fidelity.

Scattering

V-Lox provides users with a simple to use, but sophisticated, capability for analyzing scattering from virtually any object.  V-Lox provides efficient solvers for both electrically small and electrically large problems.  Since engineers typically want to know scattering over many angles of incidence, V-Lox employs a fast direct solver as opposed to an iterative method such as MLFMA.  Our fast direct solver has the additional advantage of achieving “direct solution” accuracy.  Fast iterative solvers often corrupt the magnitude and especially the phase information of the scattered field, which is particularly problematic when performing wideband analysis.  V-Lox’s fast direct solver supports accurate and efficient solutions for both narrowband and wideband analysis.

Microwave Circuits

Many devices require analysis with a rigorous EM solver due to the electrical size of the components involved.  V-Lox is capable of outputting Y, Z, and S-parameters for arbitrary N-port networks as well as calculating near fields and radiating fields for virtually any passive microwave device.  V-Lox’s fast direct solver allows rigorous analysis of electrically large networks and accurate computation of S-parameters, notoriously difficult problems for iterative solvers.
