A continuum meshfree method for sandbox-style numerical modeling of accretionary and doubly vergent wedges

A Mass Conservative Method for Numerical Modeling of Axisymmetric flow

In this paper, the cell-centered finite volume method (CC-FVM) has been presented to simulate the axisymmetric radial flow toward a pumping well. The model is applied to the unstructured triangular grids which allows to simulate inhomogeneous and complex-shaped domains. Due to the non-orthogonality of the irregular grids, the multipoint flux approximation (MPFA) methods are used to discretize t...

8. Growth of Accretionary Wedges off Vancouver Island and Oregon

A simple formulation for the growth of a wedge of constant taper accreting a sediment layer of given thickness and exponential decrease of porosity with depth was used to estimate the rates of growth of the accretionary wedges off Vancouver Island and Oregon. Application to the section off Vancouver Island indicates that the accreted sediments penetrated at Site 889 were added to the toe of the...

Effects of oceanic ridge subduction on accretionary wedges: Experimental modeling and marine observations

Sandbox modeling is used to study the deformation of accretionary wedges caused by the subduction of oceanic ridges. The first experiment incorporates a massive ridge within a sand wedge. The wedge thickens and shortens when the forward propagation f the basal decollement ceases. The wedge thickening results in taper change, reactivation of preexisting thrusts, and retreat of the frontal part o...

Thrust wedges and fluid overpressures: Sandbox models involving pore fluids

A meshfree numerical method for acoustic wave propagation problems in planar domains with corners and cracks

The numerical solution of acoustic wave propagation problems in planar domains with corners and cracks is considered. Since the exact solution of such problems is singular in the neighborhood of the geometric singularities the standard meshfree methods, based on global interpolation by analytic functions, show low accuracy. In order to circumvent this issue, a meshfree modification of the Metho...
