Worked on the APSIS-ANALYSIS/PERIGEE repository, delivering core enhancements to finite element analysis workflows over four months. Focused on improving solver robustness, numerical accuracy, and code maintainability, the work included refactoring C++ code for better memory management, expanding test coverage, and streamlining mesh processing for fluid-structure interaction. Addressed bugs affecting simulation reliability, such as pressure variable handling and uninitialized data, while introducing features that simplify configuration and data logging. Leveraged C++, parallel computing (MPI), and scientific computing techniques to reduce runtime risk, prevent memory leaks, and ensure accurate, reproducible results in complex elastodynamics and fluid dynamics simulations.

Jan 1, 2025January 2025 APSIS-ANALYSIS/PERIGEE monthly summary focusing on stability, maintainability, and configuration clarity. Delivered fixes and refactors that reduce runtime risk and streamline data handling for FSI workflows. Key changes include: fixing an initialization bug in FEAElement_Triangle3 to prevent undefined behavior, refactoring mesh management for FSI by passing essential mesh counts to the Part_FEM_FSI constructor to simplify partitioning and data handling, and removing an obsolete input file (linearPDE_input.yml) from linearPDE examples to reflect the updated configuration approach. These changes improve runtime reliability, speed up preprocessing, and reduce configuration confusion for future deployments.
