CrusDe is a plug-in based simulation framework to study effects due to changes in loads resting on the Earth's surface. Such changes could for example involve a melting glacier, oscillating snow loads, or lava flows. The focus in the simulation could be the response of the Earth's crust in terms of stress changes, changes in strain rates, or simply uplift or subsidence and the respective horizontal displacements of the crust (over time). Users are enabled to:
CrusDe implements Green's method in which a unit impulse response is convolved with a forcing function. Realizations of its model elements are independent and exchangeable on the basis of a plug-in approach. Experiment definitions are given in XML files. To this point CrusDe can simulate everything it was given a unit impulse response.
CrusDe's plug-in mechanism aims for straightforward extendability allowing modelers to include, for example, yet not supported Earth models. Current Green's function implementations:
can be combined to express:
that can have independent load history and crustal decay functions
