Viscoelastic Fluid Modeling for Geophysical Applications in an Eulerian Framework
… upper mantle exhibit elastic behavior on short timescales and viscous behavior on long timescales, motivating the use of viscoelastic models for intermediate regimes. Such models are essential for capturing both stress accumulation and permanent deformation but are highly nonlinear and …

A Finite-Element Coarse-GridProjection Method for Incompressible Flows
… discretizations as well as explicit time integration methods. In this article we present for the first time a version of CGP for finite element discretizations, which uses a semi-implicit time integration scheme. The mapping functions correspond to the finite-element shape functions. …

The numerical solution of free surface problems for incompressible Newtonian fluids
… approach for the solution of two-dimensional, time-dependent, surface-tension-driven free-surface flows involving domains of arbitrary shape that may undergo large changes in shape during the course of a problem. Both Stokes and Navier-Stokes problems are considered, a mixed Lagrangian-Eulerian …

Numerical simulation of nonlinear response of moored floating structures to steep waves
… of the calculation and is moved at all other time steps in order to conform to the motion of the free surface and structures. This feature allows one to use an unstructured mesh with any degree of complexity without the need of regenerating it every time step, which is generally inevitable and …

A Lagrangian, Discontinuous-Galerkin Material Response Solver for the Analysis of Ablative Thermal Protection Systems
… mass transfer. The numerical solution employs a semi-implicit time integration scheme for the nonlinear heat and mass transfer problems, while the solid mechanics is addressed using dynamic relaxation. Importantly, a mesh recession algorithm is implemented to explicitly account for changes in …
