4.4 TRUSS NO.4 IN SPACE

The truss element No.4 can take any location in space. It is part of the simplest elements in Z88 and is calculated extremely fast. The truss elements matches Hooke's law exactly .

Input:

CAD (see chapter 2.7.2): Line from node 1 to node 2

Z88I1.TXT

> KFLAG for cartesian (0) or cylindrical coordinates (1)

> 3 degrees of freedom for each node

> Element type is 4

> 2 nodes per element

> Cross-section parameter QPARA is the cross-sectional area of the truss

Z88I3.TXT

Trusses No.4 have no influence. However, Z88I3.TXT must exist (with any content).

Results:

Displacements in X, Y and Z

Stresses: Normal stresses

Nodal forces in X, Y and Z for each element and each node.
