pffdtd (fork)

Wave-based FDTD solver for room acoustics — fork with CUDA optimizations, a cross-validation reference for RaySound.

Fork of: bsxfun/pffdtd — Brian Hamilton, University of Edinburgh, 2021

A fork of Brian Hamilton's FDTD simulator (MIT). The changes are confined to the CUDA GPU engine: native-architecture builds, real multi-GPU peer access, batched source injection, block-wise read-out. The numerical scheme is unchanged — the forward output matches the reference Python engine to machine precision. ST-LINE maintains it as an independent wave-based tool to cross-validate, method against method, the DG engine of RaySound.
