V15 127 New - Zeland Ie3d

Version 15 refined the Adaptive Frequency Sampling (AFS) algorithm. For structures with highly resonant behavior (e.g., filters or patch antennas), the new AFS logic reduces the number of frequency points required to generate an accurate S-parameter response, speeding up the total simulation time by up to 40% in specific use cases.

Keywords covered: zeland ie3d v15 127 new, IE3D GPU solver, MoM hybrid FEM, planar EM simulation, antenna design software.

Last updated: March 2025. All benchmarks run on an Intel i9-13900K, 64 GB DDR5, NVIDIA RTX 4080. zeland ie3d v15 127 new

For non-planar structures (e.g., curved radomes, plastic enclosures), v15.127 now seamlessly couples MoM with a limited-region FEM solver. This means:

IE3D (Integral Equation 3D) employs the Method of Moments (MoM) with a full-wave Green’s function, making it efficient for layered planar structures. Version 15.x marked a transition toward hybrid meshing and GPU acceleration. Version 15.127 consolidates bug fixes and introduces several user-demanded enhancements.
