Line Meshing

1D mesh allows accurate testing of connectors (such as bolts) and similar rod-like or bar-like objects that can be modeled as a simple line for FEA purposes.

One-dimensional elements currently supported include bar2s, bar3s, rigid links, rbe3s, plots, rigids, rods, springs, welds, gaps, and joints. The following list indicates the storage capabilities and purpose of each of the 1D elements.

1D Element

Stores

Purpose

Bar2

A property reference

A local axis vector

Pin flags

Offset vectors

Optional orientation nodes

Supports complex beams.

Bar3

Property reference

Local axis vector

Pin flags

Offset vectors

Optional orientation nodes

Supports complex beams.

Note:

bar3s contain a third node designed to supported second order beams.

Gap

Property reference

Supports gap elements.

Joint

Property reference

Optional orientation nodes or system(s)

Supports kinematic joint definitions supplied with Safety Analysis Codes.

Plot

A reference to two nodes

Supports display type elements.

RBE3

A degree of freedom at each node

Weight at each node

Supports NASTRAN RBE3 elements.

Rigid link

A degree of freedom code

One independent node

Multiple dependent nodes

Supports rigid elements with multiple nodes.

Rigid

A degree of freedom code

Supports rigid elements.

Rod

A property reference

Supports simple beams.

Spring

A property reference

A degree of freedom code

An optional orientation vector

Supports springs or damper.

Weld

A degree of freedom code

Supports weld elements.
