This chapter provide the theoretical formulations and numerical procedures involved in hydro-mechanical coupling function in FRACOD.
An explicit iteration approached is used in FRACOD to solve the coupled fracturing – hydraulic flow processes. The mechanical calculation (including rock deformation and fracture propagation) is completed using the Displacement Discontinuity Method (DDM) with an iteration scheme for modelling fracture propagation processes. The fracture fluid flow calculation is conducted through the time-marching iteration based on the Cubic Law.
