Introduction to the ANSYS Meshing Application Mesh Specification Training Manual Purpose – For both

Introduction to the ANSYS Meshing Application Mesh Specification Training Manual Purpose – For both CFD (fluid) and FEA (solid) modelling, the software performs the computations at a range of discrete locations within the domain. – The purpose of meshing is to decompose the solution domain into an appropriate number of locations for an accurate result. – The basic building-blocks for a 3 D mesh are: Tetrahedrons (unstructured) Hexahedrons (usually structured) Pyramids (where tet. and hex. cells meet) Prisms (formed when a tet mesh is extruded) Manifold Example: Outer casting and internal flow region are meshed for coupled thermal/stress gas flow simulation ANSYS, Inc.

Introduction to the ANSYS Meshing Application Mesh Specification Training Manual Considerations • Detail: – How much geometric detail is relevant to the simulation physics. – Including unnecessary detail can greatly increase the effort required for the simulation. Is it necessary to resolve this recess? • Refinement – Where in the domain are the most complex stress/flow gradients? These areas will require higher densities of mesh elements.

Introduction to the ANSYS Meshing Application Mesh Specification Training Manual • Quality – In

Introduction to the ANSYS Meshing Application Mesh Specification Training Manual • Quality – In areas of high geometric complexity mesh elements can become distorted. Poor quality elements can lead to poor quality results or, in some cases, no results at all! – There a number of methods for measuring mesh element quality (mesh metrics*). For example, one important metric is the element ‘Skewness’. Skewness is a measure of the relative distortion of an element compared to its ideal shape and is scaled from 0 (Excellent) to 1 (Unacceptable). 0 -0. 25 -0. 50 -0. 80 -0. 95 Excellent very good acceptable 0. 95 -0. 98 bad 0. 98 -1. 00 Unacceptable *Further information on mesh metrics is available in the documentation and training lecture appendices ANSYS, Inc.

Introduction to the ANSYS Meshing Application Mesh Specification Training Manual Example showing difference between good and poor meshes: This example illustrates an unconverged thermal field in a manifold solid casting. On closer inspection it is clear that the simulation is unable to resolve a sensible data field in the region of poor quality elements. The example with good quality elements demonstrates no problems in the solution field. The ANSYS Meshing Application provides many tools to help maximise mesh quality ANSYS, Inc.
