    ANSYS 14.0 Meshing Advances

  • © 2011 ANSYS, Inc. February 22, 201220

    Rapid & Robust Meshing

    Top on the list of challenges

    engineering companies are facing is

    shortened product development

    schedules while at the same time the

    product designs themselves are

    becoming increasingly complex.

    Meshing of these designs introduce

    challenges in terms of speed,

    robustness and accuracy.

    Virtual Topologies (VT) enabling improved automation, flexibility, and usability:

    • More interactive usage through direct graphics interaction rather than tree objects

    • Ability to run “Auto VT” on selected edges, faces or bodies

    • Clustering of faces/edges

    • Create hard vertex

    • Face splits

    • Improved meshing performance w/VTs
