Analysis of a high order Trace Finite Element Method for PDEs on level set surfaces
, 2016 We present a new high order finite element method for the discretization of partial differential equations on stationary smooth surfaces which are implicitly described as the zero level of a level set function.

Adaptive vertex-centered finite volume methods with convergence rates
, 2016 We consider the vertex-centered finite volume method with first-order conforming ansatz functions. The adaptive mesh-refinement is driven by the local contributions of the weighted-residual error estimator.

The Finite Volume Element Method for Time Fractional Generalized Burgers’ Equation
Fractal and FractionalIn this paper, we use the finite volume element method (FVEM) to approximate a one-dimensional, time fractional generalized Burgers’ equation. We construct the fully discrete finite volume element scheme for this equation by approximating the time ...
