| Zusammenfassung |
| A method for incorporating multi-resolution capabilities within pre-existing
global 3-D spherical mantle convection codes is presented. The method, which
we term "geometric multigrid refinement", is based upon the application of
a multigrid solver on non-uniform, structured grids and allows for the
incorporation of local high-resolution grids within global models. Validation
tests demonstrate that the method is accurate and robust, with highly
efficient solutions to large-scale non-uniform problems obtained.
Significantly, the scheme is conceptually simple and straightforward to
implement, negating the need to reformulate and restructure large sections of
code. Consequently, although more advanced techniques are under development
at the frontiers of mesh refinement and solver technology research, the
technique presented is capable of extending the lifetime and applicability of
pre-existing global mantle convection codes. |
