Workshop 4.2  Mapped Face Meshing for a Swept Mesh

Different types of analyses have different meshing requirements
Structural – coarser mesh with higher order elements
CFD – finer, smoothly varying mesh, boundary layer resolution
Different CFD solvers have different requirements as well
Explicit Dynamics – uniformly size mesh desired
  Possible to set common defaults by setting the Physics Preference
