Atomistic to Continuum Multiscale and Multiphysics Simulation of NiTi Shape Memory Alloy
… due to the application of temperature and/ or stress (/strain). Among different SMAs, NiTi is a popular one. NiTi shows reversible phase transformation, the shape memory effect (SME), where irreversible deformations are recovered upon heating, and superelasticity (SE), where large …

Stabilized Finite Elements and a Domain Decomposition Method for First-Order Transient Problems
… which is a highly desirable feature in the multiscale and multiphysics simulations. One of the advantages of the method is that existing software and numerical techniques can be used to solve each subdomain separately. The proposed coupling method provides a powerful approach not only to …

Hybrid Eulerian/Lagrangian 3D methods for high Reynolds number reactive flows
… especially with regard to stability, emissions, and power density. Examining combustion dynamics and control using numerical simulations, however, presents several challenges, given the multiscale and multiphysics nature of the underlying flows. This thesis presents progresses in combustion …

Efficient Time Stepping Methods and Sensitivity Analysis for Large Scale Systems of Differential Equations
Many fields in science and engineering require large-scale numerical simulations of complex systems described by differential equations. These systems are typically multi-physics (they are driven by multiple interacting physical processes) and multiscale (the dynamics takes place on vastly …
