  • Easy movie generation for interpreting results

  • UI-driven experience – no scripting required

  • Importing mine geometries for different stages of excavation allows for quick and easy automatic generation of staged geomechanical analysis.  Hundreds of stages can be set up in seconds.

  • Easy specification of material properties and in-situ stresses through dialogs.  Meaningful defaults provided.

  • Common boundary conditions applied with one or two clicks

  • Simple model mesh creation (octree)

  • Extensive help system including dozens of how-to videos

  • Movie templates provided for easy creation of movies of common views (e.g. stress, displacement)

  • Querying of stresses or displacements at specified points can be done simply by clicking on the finished model

  • Built on FLAC3D engine

  • Combines multiple capabilities into one product

  • Block model visualization

  • Advanced seismic (option) analysis

  • Start using IMASS (option) in your mine scale modeling

  • UI driven model building and an interface targeted to mining applications makes model building faster than ever (minutes or hours instead of days or weeks)

  • Use Basic mode to quickly run simple elastic or plastic models with no distractions

  • Use Advanced mode to easily construct complex models with access to all generated FLAC3D data files to learn FLAC3D and customize models


Everything You Need And More Included:

Expand your IMAT software capabilities with our included options, designed to tackle diverse engineering challenges effectively. Explore our selection of options to customize your IMAT experience.
  • Upload your seismic data directly into IMAT

  • Visualize locations, magnitudes, and the evolution of seismicity through time and space

  • Visualize seismic event moment tensors

  • Many different chart-based analyses including T-k Hudson plots and Gutenberg-Richter type b-value plots

  • Compare seismicity produced by numerical model with actual imported seismicity

  • The Itasca Constitutive Model for Advanced Strain Softening (IMASS) has been developed to represent the rock mass response to excavation induced stress changes. IMASS represents the damage around an excavation, slope, or caving process by accounting for the progressive failure and disintegration of the rock mass from intact, jointed, and/or veined rock to a disaggregated, bulked material. IMASS is based on empirical relationships and uses strain and zone-size dependent properties that reflect the impacts of dilation and bulking as a rock mass undergoes plastic deformation.
