•Usages
of shell meshing:
–Thin
sheet solid modeling (FEA) – stamped parts
–2D
cross sectional analysis (CFD)
–Input
for volume meshing (FEA/CFD) – Delaunay, Advancing Front, T-grid
–Filling
a surface mesh is faster than tetra octree but
requires well-connected geometry
• Procedure
–First
need to decide mesh setup parameters
•Mesh
method
–Algorithm
used to create mesh
•Mesh
type
–quad/tri/mix
•Mesh
sizes
–Small
enough to capture physics, important features
–Large
enough to reduce grid size (number of elements)
•Memory
limitations
•Faster
mesh/solver run
–Set
mesh sizes on parts, surfaces, and/or curves
–Based
on edge length
–Can
have different types/methods set on
different surfaces
•Surface Mesh Setup
–Same parameters as part mesh setup
but also includes:
–Mesh
type
–Mesh
method
–Select surfaces first from screen,
set sizes/parameters and Apply
–Mesh method/type will override global
shell mesh settings for selected surface(s)
–Will override Part
Mesh Setup settings if set afterward
–Display
•Right mouse, select in Model tree on Surfaces >
Tetra/Hexa
Sizes
–Icon appears for each surface
–Gives you a visual estimate of
prescribed max. size
