Local time stepping for implicit-explicit methods on time varying grids
نویسنده
چکیده
In the context of nonlinear conservation laws a model for multiphase flows where slow kinematic waves co-exist with fast acoustic waves is discretized with an implicit-explicit time scheme. Space adaptivity of the grid is implemented using multiresolution techniques and local time stepping further enhances the computing time performances. A parametric study is presented to illustrate the robustness of the method.

A parallel explicit/implicit time stepping scheme on block-adaptive grids
We present a parallel explicit/implicit time integration scheme well suited for blockadaptive grids. The basic idea of the algorithm is that the time stepping scheme can differ in the blocks of the grid for a given time step: an explicit scheme is used in the blocks where the local stability requirement is not violated and an implicit scheme is used in the blocks where the explicit scheme would...
متن کاملA General Solution for Implicit Time Stepping Scheme in Rate-dependant Plasticity
In this paper the derivation of the second differentiation of a general yield surface implicit time stepping method along with its consistent elastic-plastic modulus is studied. Moreover, the explicit, trapezoidal implicit and fully implicit time stepping schemes are compared in rate-dependant plasticity. It is shown that implementing fully implicit time stepping scheme in rate-dependant plasti...
متن کاملLocal Time Stepping Applied to Implicit-Explicit Methods for Hyperbolic Systems
In the context of systems of nonlinear conservation laws it can be crucial to use adaptive grids in order to correctly simulate the singularities of the solution over long time ranges while keeping the computing time within acceptable bounds. The adaptive space grid must vary in time according to the local smoothness of the solution. More sophisticated and recent methods also adapt the time ste...
متن کاملA New Implicit Dissipation Term for Solving 3D Euler Equations on Unstructured Grids by GMRES+LU-SGS Scheme
Due to improvements in computational resources, interest has recently increased in using implicit scheme for solving flow equations on 3D unstructured grids. However, most of the implicit schemes produce greater numerical diffusion error than their corresponding explicit schemes. This stems from the fact that in linearizing implicit fluxes, it is conventional to replace the Jacobian matrix in t...
