WHY YOU'LL LOVE IT

Why Choose MassFlow?

Explore MassFlow’s comprehensive features and user-friendly interface. Unlock powerful computing capabilities, including the ability to run two instances simultaneously. Discover why MassFlow is the ideal choice:

  • Solve for any time increment or for the entirety of the draw schedule

  • Drawpoint layout design

  • Caveability and caving rate

  • Air gap formation

  • Isolated movement zone (IMZ) and isolated extracted zone (IEZ) limits

  • Movement of caved material within the IMZ

  • Marker path tracing (displacement/day or extraction status)

  • Marker velocity vectors

  • Tonnage, ore recovery, and dilution entry

  • Primary and secondary fragmentation

  • Fines migration

  • Breakthrough timing and surface subsidence

  • Incorporate previously mined regions

  • Abutment stresses and cave loads when coupled to FLAC3D or 3DEC

  • Simply driven by four input data files:

    1. Mine block model of rock
    2. Drawpoint locations
    3. Drawpoint descriptions (conical or rectangular draw bells or sublevel cave draw points)
    4. Draw periods/schedule

  • Use a Wizard to import the input CSV files, specify model settings, and automatically generate the simulation data file commands to run uncoupled flow models

  • ITASCA’s Version 9 user interface makes it easy to tile plots, data files, and tool panes to work with and explore your simulation

  • Features an intuitive interface, offering easy navigation and seamless access to essential tools and features

  • Provides users with flexible commands and scripting options, saving time and boosting productivity

  • Data presented in a clear, understandable manner contributes to well-informed decision making

  • Promotes collaboration among multidisciplinary teams, facilitating effective communication and cooperation

  • Optimized flow marker search and sorting algorithms

  • For efficient modeling, markers are only created once the rock mass becomes unbulked

  • Multi-threaded FISH Lists and Operators to query or modify the model incredibly quickly, even while cycling

  • Advanced plotting tools to understand your model results and for working with hundreds of plots on real projects

  • FISH, ITASCA’s scripting language, provides unparalleled control and customization of the model

  • Built-in Python 3.10 scripting includes SciPy for plotting, NumPy for computing, and Pyside for UI customization

  • Most model changes (via mouse, commands, or scripting) are recorded for repeatability, learning, and re-use

  • Highly customizable user interface (UI) and modeling

  • All licenses permit two instances of MassFlow to be run simultaneously on the same computer

  • Access and modify almost all variables (including customizable “EXTRA” variables) via FISH or Python

  • Import and export any ASCII data format

MORE TO LOVE

Everything You Need And More Included:

  • Advanced modeling of isolated movement zones (IMZ) and internal material movement during incremental draw

  • Enables a detailed understanding of how material flows and evolves over time within the cave mine

  • Precise tracking of IMZ volumes by considering material bulking at the periphery

  • Controls bulking at the local level through initial and maximum porosity settings, ensuring accurate volume calculations

  • The isolated extraction zone (IEZ) is defined based on the initial positions of those markers extracted

  • Utilizes markers to track material movements within IMZ

  • Daily updates of marker positions and properties provides simulated time insights into material behavior

  • The development of air gaps is tracked through the addition of zero mass “air” markers at any location where an IMZ meets a fixed boundary to flow

  • Considers the influence of fragment size on cave shape and width

  • Provides valuable data on how rock characteristics impact movement patterns, aiding in decision making

  • Achieves uniform draw by superposition of velocity profiles when IMZs overlap

  • Enhances mining by optimizing resource recovery

  • MassFlow offers seamless integration with two of Itasca’s other powerful software solutions: 3DEC and FLAC3D. This interoperability enables comprehensive geomechanical analysis by considering factors like stress distribution and rock yielding alongside material flow dynamics

  • Mining engineers can harness the combined capabilities of MassFlow, 3DEC, and FLAC3D to perform geomechanical simulations that incorporate both material flow and stability assessments
