John Mould provides practical solutions to projects that require the development of supporting software or modules. These range from simplified engineering tools to high-fidelity analysis packages. John supervises the representation of materials in FLEX analyses and manages module development for FLEX finite element software: NLFlex for blast and impact applications, PZFlex for piezoelectric applications, EMFlex for electromagnetic wave propagation and SpectralFlex for long-range linear and nonlinear acoustic wave propagation. John formulated the constitutive model used by the Applied Science practice for analyzing concrete and rock. He oversees the development of both shared memory (OpenMP) and distributed memory (MPI) approaches, ensuring parallelism in the software. He also manages the development of fast-running engineering tools and modules. To address challenging applications that require coupled fields, he is working to enhance the coupling between the NLFlex computational structural dynamics code and the computational fluid dynamics (VCFD) code. John is also involved in the development of technologies for Life Science applications.
