Nullspace EM Release 2023.4 is available!

Release Notes here

Nullspace EM has been developed and validated by against experimental data and real-word designs for 12+ years, with a focus on simulation speed and accuracy of the results.

Fast linear algebra- based solvers are ideal for large-scale electromagnetic analysis and design. With Nullspace EM you can confidently engage in digital, model-based engineering reducing design cycle time and lowering the number of costly prototype design loops.

Key Features

  • Fast, accurate, and scalable EM simulations enabled by high-order geometry (HOG) and high-order basis functions (HOBF) reduce meshing requirements while improving simulation accuracy. HOG reduces your workflow timeline of generating optimized meshes while better representing the original, physical model.

    With HOG, simulation uncertainty due to inaccurate model representation is significantly reduced. HOG coupled with HOBF reduces the simulation size without the loss of, and often improving, solution accuracy.

  • For accurate analysis of electrically large problems, Nullspace EM offers a fast-direct solver that dramatically reduces the runtime and memory requirements without loss of accuracy. The solver is based on novel, proprietary large scale linear algebra matrix compression algorithms.

    The fast direct solver is highly accurate for wideband analysis problems such as time-domain imaging, large-scale scattering, and wideband phased arrays. Challenging simulations that are unapproachable with other solvers are transformed into your new standard for day-to-day modeling.

  • Nullspace EM employs hybrid multi-CPU and multi-GPU acceleration for both direct and fast-direct solution types. Multi-CPU/GPU acceleration comes standard with Nullspace EM transforming your simulation workflow from your first model.

    Multi-GPU acceleration yields runtime speed-ups of up to 16X based on the GPU architecture. Simulations that take hours or days for large simulations with other commercially available tools, often take minutes to hours with Nullspace EM.

  • Nullspace EM’s powerful Python scripting interface gives you complete control of every aspect of the simulation process from CAD import/creation to visualizing results. Integrating Nullspace EM into simulation workflow enables powerful parametric analysis and optimization.

    Connecting Nullspace EM to other software packages by leveraging the flexible data formats for simulation configuration and post-processing data. No longer are you beholden to a particular post-processing and visualization workflow. With the Python interface, the entire power of the Python language and the vast ecosystem of libraries and modules is at your disposal.
