    Why A Command-Driven Interface? Why FISH? 1 Check Model Runtime 2 Effects on Runtime 3 Considerations for Zoning Density 4 Automatic Detection of an Equilibrium State 5 Considerations for Selecting Damping 6 Check Model Response 7 Initializing Variables 8 Minimizing Transient Effects on Static Analysis 9 Changing Material Models
  • zone create command — Itasca Software 9. 0 documentation
    Create 3D zone-filled primitive shapes ( brick, cylinder, etc ) with a predefined grid pattern See Primitive-Based Grids for further discussion and examples of the process of creating a mesh using primitive shapes
  • block create command — Itasca Software 9. 0 documentation
    The method for block creation is determined by the first keyword used The keywords brick, drum, prism, tetrahedron or tunnel will create a block from a bounding-region shape
  • Supported Tunnel — Itasca Software 9. 0 documentation
    This example shows how to create a simple supported tunnel in fractured rock The joints are simulated using the Discrete Fracture Network (DFN) logic, and the tunnel is supported using hybrid bolts
  • Generating Block Assemblies — Itasca Software 9. 0 documentation
    Examples for generating Voronoi block assemblies for a simple cube and cylinder are shown below These examples can be found in Users_Guide block_generation voronoi
  • Grid Generation in FLAC3D — Itasca Software 9. 0 documentation
    The three tunnels are all cylindrical in shape, so the radial-cylinder primitive shape is the logical choice to build the tunnel grids A vertical symmetry plane may be assumed to exist along the centerline of the service tunnel
  • Creating Single Blocks — Itasca Software 9. 0 documentation
    The block create tunnel command is specifically designed to generate a circular-shaped tunnel model This command works by constructing the model with individual blocks
  • Example: Simple Tunnel with Hybrid Bolt Support in
    A simple circular tunnel with a radius of 1 m is simulated It is a 2 5D model with a length of 2 m Quarter symmetry is assumed This is a bonded block model in which zones are transformed into tetrahedral blocks A joint set is then imprinted on top of the bonded block assembly
  • Tutorial: Quick Start (FLAC3D) — Itasca Software 9. 0 documentation
    This tutorial steps through the actions necessary to quickly get a first FLAC3D model to solution Very little time is spent explaining the various user interface elements being used Rather, the focus is on getting something together and providing basic familiarity with the user interface
  • Rigid Block Model of Tunnel Excavation - Itasca International
    This example simulates the sequential excavation of a tunnel in a fractured rock mass Stresses are installed in the initial, zero-porosity Bonded Block Model (BBM) consistent with a tunnel at 400 m depth, where the lateral stresses are larger than the overburden stress
  • Itasca Software Guide — Itasca Software 9. 0 documentation
    It also introduces the calculation cycle, physical forces at work in the model (energy, stress and strain), and an introductory look at the components that are used to create models (zones, balls or clumps, structural elements, blocks, etc )
