XSite is a powerful three-dimensional hydraulic fracturing numerical simulation program based on the Lattice and Synthetic Rock Mass (SRM) methods.
Where joint (discontinuity) planes cut springs, the angle of the plane is respected (not the spring orientation). Thus, shear and normal compliances for the joint are used instead. In addition, slip and opening/closing of joint elements are modeled. Sliding on joint planes is independent of the local orientations of component springs.
