MultiMech-2015 Product Overview


MultiMechanics helps companies using advanced materials greatly reduce physical prototyping and testing, by letting them:

  • • Predict structural failure based on microstructural design variables, such as fiber orientation and volume fraction
  • • Virtually create and test new and existing materials with an unprecedented level of detail and accuracy, for multiple types of composites, including woven, braided, particulate, continuous and chopp ed fibers reinforced plastics
  • • Zoom into the material microstructure to find out where, when and why damage initiates
  • Multimech is an all-inclusive, Multiscale Finite Element software
    package for composite structural analysis.

    Our unique TRUE Multiscale™ technology extends all the design flexibility and robustness of Finite Element Modeling down to the microstructural level, strongly coupling macro and micro mechanical response.

    Key Features

    • • Model the effect of individual microscale constituents, their interactions, volume fractions, spatial distribution and orientation, fracture toughness, among other factors, are explicitly incorporated into the design process
    • • Perform implicit and explicit, multiscale finite element analysis
    • • Multiscale nesting scheme allows modeling of unlimited number of scales, e.g., structural part + fiber reinforced material + resin reinforced with nanoparticles
    • • Advanced algorithm allows for accurate damage modeling, including multiscale transition of micro-cracks into macrocracks
    • • Factor injection molding orientation data into your analysis
    • • One-click virtual test for quick and easy predictions of material behavior
    • • Fully parallelized on both standard multi-core Desktops/Laptops and HPC infrastructures
    • • Simulate additive manufacturing such as 3D printed parts and phase construction of cement concrete
    • • Automatic Generation of Complex, 3D Finite Element Microstructures
    • • Available as standalone software or as a Plugin for most major CAE Platforms
