1. Installation & License Check | Step | Action | |------|--------| | 1.1 | Download the installer from the Rocscience portal (requires a valid account). | | 1.2 | Run the installer (choose default folder, e.g., C:\Rocscience\Phase2Crack ). | | 1.3 | Launch the program once; the license manager will pop up. Verify that a Phase2Crack 6.7 license is listed. If not, contact your administrator or Rocscience support. | | 1.4 | (Optional) Create a desktop shortcut for quick access. |
2. Project Set‑Up 2.1 Create a New Project
File → New (or click the “New” toolbar icon). Choose a working directory – this is where all input, output, and log files will be saved. Give the project a descriptive name (e.g., Tunnel_Excav_2D_Stage1 ).
2.2 Define Units
Go to Options → Units . Select the unit system you prefer (SI, US, or Custom). Verify that length, stress, and displacement units are consistent (e.g., meters, MPa, meters).
2.3 Set the Analysis Type
In the Project → Analysis Type dropdown, select “Crack Propagation (Phase2Crack)” . Choose 2‑D Plane Strain or 2‑D Axisymmetric depending on geometry. (Version 6.7 does not support full 3‑D.) i--- Rocscience Phase 2 Crack- 67
3. Geometry Creation 3.1 Define the Model Boundary | Tool | Use | |------|-----| | Rectangle / Polygon | Draw the outer limits of the rock block (e.g., 30 m × 20 m). | | Circular/Arc | Create cavities, boreholes, or tunnels. | | Import DXF | If you have CAD geometry, import it (make sure it’s 2‑D). |
Tip: Keep the boundary at least 3–5 times the expected fracture length away from the zone of interest to avoid boundary effects.
3.2 Add Pre‑Existing Discontinuities
Line/Polyline → draw a line where a joint or fault already exists. Assign a joint property set (see Section 4). Use “Split” if you need the line to cut the mesh (important for initial cracks).
3.3 Define Excavation or Loading Zones
