Numerical simulation of magma intrusion

Based on the user_HydraulicBlock example, a two-dimensional magma intrusion model is established. The model contains 31,000 solid units and 47,000 fluid units. A weak interlayer is established in the middle and lower part, which also has a higher permeability. A circular area is excavated from the lower part as a "magma room".

Initially, the units are cemented with each other, and the permeability after the cement fracture is set to increase by 100 times. A constant pressure of 5MPa is applied to the upper part of the rock formation, and a constant pressure of 100MPa is applied in the "magma chamber". Simulate fracture formation and fluid migration. Using a laptop computer for calculation, the simulation takes 2 hours and the simulation real world time is 26.4 seconds.
