Passage DEM Software

Passage®/Compression Software

  • PASSAGE/COMPRESSION software  is a finite element program for the mold filling simulation of complex three-dimensional, thin-walled parts.
  • Flow models include: Barone-Caulk hydrodynamic friction and generalized Newtonian fluid to simulate the non-isothermal filling of SMC, BMC, and glass; fiber orientation for SMC and curing kinetics for thermosets. 
  • A high-pressure in-mold coating simulation option is also available. 
  • A user-friendly preprocessor allows mesh generation and capability to accept externally generated
  • meshes with interactive entry of process conditions and numerical control parameters. 
  •  Results are viewed with an interactive post-processor that features dynamic rotation and zooming animation of results, and viewing options for color contour and vector plots.

Features

  • Isothermal and non-isothermal analyses
  • Hydrodynamic friction model
  • Generalized Newtonian material models
  • Fiber orientation prediction
  • Post-filling curing analysis to determine the gel time
  • Orthotropic mechanical property prediction
  • Ability to interface with anisotropic stress analysis
    programs for warpage and structural integrity of parts
  • Mesh generator, and accepts meshes from other
    structured or unstructured mesh generation programs
  • Boundary and process conditions entered interactively
    for all types of meshes, including the placement of initial
    charge patterns
