Pedro Osorio developed version-specific handling for HEIDI within the multifluid IM-GM coupling in the SWMFsoftware/SWMF repository, focusing on improving simulation correctness when HEIDI is active. He updated the CON_couple_gm_im.f90 module to conditionally set NameVar and nVarImGm based on NameVersionIm, ensuring the appropriate variables are used for each version. This Fortran-based enhancement addressed potential variable mismatches and improved runtime stability for HEIDI-enabled runs. Leveraging his skills in numerical simulation and scientific computing, Pedro’s work laid a solid foundation for consistent multi-version support, demonstrating a thoughtful approach to maintainability and correctness in complex scientific codebases.
