Relative Error Tolerance

This release contains the following updates:

• implemented relative error tolerance based on a user-defined estimate of potential or gradient magnitude (likely obtained from the previous step of a time-stepping or iterative algorithm)
• cleaner branch structure (which is why this is a breaking change)

Fully Automated Tuning

This release includes the following features:

• fully automated tuning with the tune_fmm function
• more conservative error constraint algorithm
• Fast Gauss Seidel solver as published in AIAA Aviation Conference 2024 (doi:10.2514/6.2024-4018)
• new data structures to avoid sorting the user defined system when generating the octree and to improve type stability
• lockless multithreading (on CPU)
• easy installation via the Julia Registry

Dynamic Expansion Order

Implement dynamic expansion order selection based on error tolerance.

Use O(p^3) multipole-to-local transformation

v0.3.0

v0.3.0

GPU for direct calculations

This release uses a syntax to make it possible to offload direct interactions to GPU.

Fast Gauss-Seidel Solver with FLOWPanel (tmp)

Temporary version for developing FLOWPanel with the Fast Gauss-Seidel solver (doi:10.2514/6.2024-4018).
