This example demonstrates MUFITS capabilities for modelling the brittle-ductile transition. The example requires application of the options for modelling of the plastic behaviour of rocks at elevated temperatures and hydraulic fracturing at elevated pressures. A cross-sectional model of the Earth crust is considered. A quite high geothermic gradient causes hydrothermal convection in the shallow brittle zone of the crust. From below the convection is limited by the brittle-ductile transition. The transition is perturbed with the ascending and descending plumes of the convective flow. Several cases are considered which include 1D calculation of the steady-state depth-dependent profiles and 2D examples demonstrating the convection as well as a localized fluid and heat flux from a degassing magma body influence on the transition zone.
