Wavesim Python Release

October 2024: We released a Python implementation of Wavesim v0.1.0 - alpha for solving the Helmholtz equation through domain decomposition. With this new framework, we simulated a complex 3D structure of a remarkable 315×315×315 wavelengths (3.1⋅10^7) in size in just 379 seconds by solving over two GPUs, 1.93 times the size of the largest simulation on a single GPU without domain decomposition.

Matlab Software Update

March 2024: A new version of Wavesim was released on February 27 on GitHub. The main feature of the new version is the use of a CUDA-based acceleration module (cumex) that can provide speed-up optimisation of up to x2 times.
