ICEM CFD / AI*E OverviewICEM CFD / AI*E Overview
• Available inside ANSYS Workbench (Advanced Meshing app.), or standalone
• Targeted at high-end analysts, with specific needs for meshing which handles:– Complex geometry– Dirty geometry– CAD and STL geometry– Hand-crafted mesh– 3rd party solvers

Workbench - Guiding PrinciplesWorkbench - Guiding Principles
• CAD-connected (but agnostic)• Parametric• Persistent• Highly-automated meshing• Meshing that’s aware of the applied physics• User has ability to “drill down” to control mesh
methods, controls• Independents zones are “neighbor aware”

Enhancements to the SolversEnhancements to the Solvers
• New trajectory based 3D contact algorithm– Increased flexibility (no external gap)– Significant efficiency improvements
• Group Contact (in addition to Part Contact)– Select faces to participate in contact– Erosion redefines face
• Extended material models for ANP-Tet• Automatic Mass Scaling– Courant–Friedrichs–Lewy (CFL) time step saved
for each element. (Maximum scaling: 100)• New pressure equilibrium option for Euler • HP-MPI message passing for Parallel Processing
