During February 2025, Juan Ruiz focused on enhancing the robustness of flux surface contour generation and IMAS data reading in the pyro-kinetics/pyrokinetics repository. He addressed data length inconsistencies and invalid values in equilibrium calculations by ensuring the R, Z, and psi_RZ arrays maintained consistent dimensions and by implementing logic to skip invalid flux surface entries. Using Python and leveraging skills in data analysis and scientific computing, Juan also introduced clamping of psi values to valid boundaries, which improved data integrity. These targeted improvements reduced runtime errors and increased the reliability of downstream simulations, reflecting careful attention to technical detail.
