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.

Assembly Meshing enables dramatically reduced time to mesh for typical CAD models by eliminating the tedious geometry clean‐up

Top‐down approach to mesh all parts at once• Uses Virtual Bodies (material points or groups) to automatically extract internal regions from assemblies

• Supports:– Meshing solids from sheet bodies– Conformal mesh between parts without requiring multibody parts

– Overlapping bodies– Tet (linear) and CutCell (hex‐dominant) mesh types

– Inflation

Summary

ANSYS 14.0 contains a wide range of enhancements:

• New infrastructure for flexible coupling between solvers to enable multiphysics and system level simulations

• Faster and robust solvers with highly scalable HPC for solving ever larger and more complex models with high fidelity and accuracy in less time

• Enhanced workflow and usability for greater user experience and productivity
