Release Notes
Nullspace Prep & EM 2025 R1 Release
AI-Powered CAD Cleanup
AI-based automation features automatically identify common mechanical features enabling RF engineers to perform CAD cleanup directly within Nullspace Prep, eliminating the need for back-and-forth iteration with mechanical engineering teams and external CAD tools.
Fast Adaptive Frequency Sweeps (FAFS)
Delivers up to 100X speedup in wideband frequency analysis for applications including antenna on-body performance analysis, phased array element patterns, and wideband feed network design. Users specify only the start and end frequencies; the FAFS algorithm determines optimal sample points using physics-informed interpolation that captures the true frequency-domain behavior of the structure.
Passive Circuit Loads
Enables engineers to incorporate lumped impedance elements directly within full-wave electromagnetic simulations. Engineers can now perform rapid optimization of impedance matching networks and evaluate system-level performance without requiring separate circuit co-simulation tools.
Nullspace Prep & ES 2025 R1 Release
High-order basis functions
High order basis functions allow for faster, more accurate solutions with reduced memory. Solve larger geometries on the same computational resources with same or better accuracy than previous versions.
Improved post-processing performance
Post-processing is dramatically faster, allowing high-resolution potentials and field calculations on dense grids in a fraction of the time. Perform rapid design iterations, parameter sweeps, and large-scale field analyses that were previously impractical.
Improved solver performance
Dense and compressed solver performance increased while maintaining accuracy.
Nullspace ES 2024 R1 Release
Improved meshing
Implemented a new, faster, and more efficient meshing algorithm to assure high accuracy results.
Nullspace's meshing technology is tailored for the ion trap community and efficiency in both meshing time and meshing quality for improved speed and accuracy.
Double ground planes
The newly added double ground plane symmetries can be used in combination with the geometric symmetry features including planar and rotational symmetries.
Leveraging these new symmetry workflows can speed up simulations and reduce memory requirements by factors of up to 16X.
Additional Systems Support
Extended support now includes Red Hat Enterprise Linux 9 and Ubuntu.
Nullspace Prep & EM 2023 R3 Release
Improved 3D visualization
Better visualization support for Paraview
Improved Windows support
Improved Windows support provides increased stability and performance.
Nullspace Prep & EM 2023.9 Release
Windows support for Prep and EM (Beta)
