Passage^®/Compression Software

Overview

• 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
