Nov 1, 2025November 2025 performance summary for xpsi-group/xpsi: Delivered enhanced physical realism in accretion disk simulations by adding a ray-blocking feature that accounts for oblate star geometry and Schwarzschild-radius-based blocking, improving accuracy of accreting atmosphere modeling. Fixed a blocking-related bug by using cell-dependent b and r_g values for oblate-star geometry, increasing geometry fidelity. Updated documentation, changelog, and release notes, and expanded the accretion disk tutorial with new examples to support adoption. Overall impact includes higher fidelity simulations, more reliable results for researchers, clearer release communication, and reduced maintenance overhead through improved comments and versioning. Technologies/skills demonstrated include ray tracing algorithms, oblate geometry handling, Schwarzschild-radius concepts, codebase maintenance, documentation tooling, and release management.
