• Mesh topology: FE Mesh Topology • Tet elements have poorer results (automatic generation) • Hex elements have much better results (harder to generate mesh) • STRIPE requires Hexahedral elements • (15-node Wedge elements are also allowed) Hex-20 Tet-10 12/35
FE Mesh Design • Typical FE mesh design s<strong>of</strong>tware requires part division into 5 or 6 sided components for Hex mesh • Highly time consuming • Unique FE mesh s<strong>of</strong>tware to expedite Hex mesh generation (TrueGrid®) 13/35
