Description

Creates a mesh of all the surfaces contained in a model.

Syntax

struct = MESH( model, elem_size ) ;

struct

 The structure object.

model

 The model to be meshed.

elem_size

 The desired size (side length) of elements.

Comments

This operator creates mainly quadrilateral elements but it also inserts some triangles.  A part is created for every surface of the initial model.  The nodes created at surfaces' common edges are also common for the meshes (no nodes merge is needed).  This operator meshes all surfaces contained in the model, regardless of whether they are selected or not.

The operator creates also some Nastran files containing its results:

airbag.nas

 The mesh of the model.

unfolded-mesh.nas

If the model has been obtained by folding, an ''unfolded'' mesh is written into this file. This mesh may be used for the reference-metrics method.

unfolded-geom.nas

Under the same condition as above, the ''unfolded'' geometry (but with all cuts resulting from the folding process) is written into this file. This geometry may be used for meshing with a third-party meshing program.
