John Mould manages projects that require the development of supporting software or modules, providing practical solutions that range from simplified engineering tools to high-fidelity analysis packages. He supervises work on FLEX, Thornton Tomasetti’s family of proprietary finite-element software, including modules for blast and impact, piezoelectric, electromagnetic-wave, and acoustic-wave applications. John formulated the constitutive model used by our Applied Science practice for analyzing concrete and rock. His work also includes developing fast-running tools that support engineering analyses. John oversees the development of both shared memory (OpenMP) and distributed memory (MPI) approaches, allowing software to perform computations simultaneously across multiple processors and machines. For challenging fluid–structure interaction problems, he is working to enhance the connection between the NLFlex computational structural dynamics code and VCFD, Thornton Tomasetti’s computational fluid dynamics software.
