How to mesh FEM using Patran
How to mesh FEM using Patran
(OP)
Hi everyone!
I am newbie to MSC Patran and wanted use Patran for meshing purpose. I have an irregular 2-D region(of say 6 linear edges) and two important locations(points) inside it. I wanted to mesh the surface with Quad elements all region but with fine-mesh near those two points. Can someone give some steps to follow:
Your help will greatly acknowledged !

Create>surface>trimmed
Associate>point>surface
Create Mesh Surface>use paver sub-options

Just a quick question, to have finer mesh at the two locations inside the region, do I need to make another 2 surfaces..and mesh them with shorter global length..Is there other ways to specify the paver to apply two types of meshing option in a single Big surface.
thanks in advance

Put a coarse mesh seed on the surface outer boundary
Specify a much smaller default element size
Use the p-element sub-option on the paver.
Use 'modify mesh smooth' to straighten out the mesh
This will create a graduated mesh from coarse at the boundary to fine at the point. If that is still not good enough then put a small surface around the point and create a central patch and an outer annulus. Trimmed surfaces can have inner and outer boundaries (i.e. holes)
