PRESENT DIAGRAM [[FACTOR] Factor]

          

This command provides for beam graphs to be superimposed on the mesh.

Beam elements can be graphed in three ways:

1.

For element nodal results; a graph can be displayed showing the variation of the currently selected results component at the nodes of the elements.

2.

For Gauss point results; a graph can be displayed showing the variation of the currently selected results component at the Gauss points of the elements.

3.

For element nodal results, where loading information is available for beams and the element nodal results have the correct result types; FEMVIEW will calculate and display the appropriate shear force or bending moment diagram.

Notes:

1.

Scale factor
If no scale factor is specified FEMVIEW will scale the vectors so that the length of the maximum vector, if viewed normal to its length will be approximately 10 mm. The scale factor calculated by the program is displayed. This should be used as a basis for new factors.

2.

Axes system convention
The positive direction is determined from the local X-direction (from node 1 to node 2), and the Z-direction (out of the screen), with the positive Y-direction as for a right-handed system. For example, if the beam is defined from left to right on the screen the positive values will be above the beam and the negative values below the beam.

Examples:

The graphs for all the beams are superimposed on the mesh.
