Finite Elements in Patran allows the definition of basic finite element construction. Created under Finite Elements are the nodes and element topology.
For more information on how to create finite element meshes, see
Mesh Seed and Mesh Forms (p. 25) in the Reference Manual - Part III.
Nodes
Nodes in Patran will generate unique NODE__/_ data entries. Nodes can be created either directly using the Node object, or indirectly using the Mesh object. Note that unconnected Nodes may be used in a PAMCRASH model to define beam orientations and the optional centre of gravity nodes of rigid bodies. These nodes should not be deleted.
Elements
Finite Elements in Patran assigns element connectivity, such as Quad/4, for standard finite elements. The type of PAMCRASH element to be created is not determined until the element properties are assigned. See
the
Element Properties Form for details concerning the PAMCRASH element types. Elements can be created either discretely using the Element object or indirectly using the Mesh object.
Note: | Previous versions of the Patran PAMCRASH Preference would translate tri-elements as degenerate quads in the analysis file “Which would be read back into the Patran database as tris”. This version of the preference translates tris as tris in both directions of translation. Similarly degenerate quads are translated as degenerate quads in both directions of translation. |
