Riju Dutta focused on enhancing the numerical stability of gradient computations in the pyro-kinetics/pyrokinetics repository during November 2024. Addressing a bug in the species module, Riju replaced the use of np.isclose() with np.allclose() to ensure that all elements are near zero before division, thereby reducing the risk of unstable gradients and preventing NaN or Infinity values in downstream workflows. This targeted fix, implemented in Python and leveraging skills in numerical and scientific computing, improved the reliability of simulation and optimization routines. The work demonstrated careful attention to numerical robustness, though no new features were introduced during this period.
