| Problem | Why it happens | Quick fix | |---------|----------------|-----------| | Non‑convergence after the first load step | Joint stiffness too low → contact algorithm “jumps”. | Increase normal stiffness, add a small penalty damping (0.05–0.1), or reduce the load increment. | | Crack‑Top “sticks” (no opening) even under large tensile load | Friction angle set too high or tensile strength > 0. | Set Friction = 0° for pure tension tests, or lower the Tensile Strength to a realistic value (< σ_t). | | Mesh distortion near the crack | Very coarse mesh + large deformations. | Refine the mesh locally, or enable Remeshing (available in the latest RS2 2025+ builds). | | Unexpected “locking” of the joint | Contact damping too low → oscillations that the solver interprets as “stuck”. | Raise Contact Damping to 0.1–0.2. | | Energy not conserved (large artificial energy spikes) | Incompatible time step in dynamic runs. | Use adaptive time stepping, or manually halve the Δt. | | Results look “symmetric” even though load is eccentric | Model symmetry (mirrored boundary conditions) overriding load. | Double‑check that only the desired side has the point load; disable symmetry planes if you need an asymmetric response. |

| Feature | What it does | Why it matters | |---------|--------------|----------------| | Crack‑Top Modelling | Allows you to define a thin, pre‑existing fracture (or a set of fractures) that can open, slide, or close under loading. The fracture is represented by contact elements (normal and shear stiffness, cohesion, friction, tensile strength, etc.) that are embedded in the 3‑D mesh. | Real rock masses rarely behave as a continuous solid. Joints, bedding planes, faults, and induced cracks dominate deformation and failure. Crack‑Top gives you a physically realistic way to let those discontinuities dictate the response. | | Top‑Surface Release | The “top” part of the model (usually the ground surface) can be released from the underlying rock mass, letting it separate from the crack plane. This mimics ground‑surface collapse, landslides, or roof fall. | You can simulate roof‑fall in a mine or surface subsidence above a tunnel without having to remesh the whole domain. | | Automatic Crack Propagation (optional) | When you enable the Crack Propagation option, RS2 will grow the crack based on a user‑defined fracture energy or stress‑intensity criterion. | Useful for studying how an existing joint might extend under blasting, hydraulic fracturing, or progressive loading. |

Bottom line: Crack‑Top is the bridge between a classic continuum model and a full discrete‑element approach. It’s cheap computationally, yet captures the essential physics of discontinuities.

RS2, developed by RocScience, is designed to analyze stress distribution and deformation in rock masses. It uses a finite element method to simulate the behavior of rock and soil masses. The software is particularly useful for modeling complex geological conditions and can handle a variety of rock mechanics problems, including:
