eldisp2¶

Purpose:

Draw the deformed mesh for a two dimensional structure.

Syntax:

[sfac] = eldisp2(Ex, Ey, Ed)
[sfac] = eldisp2(Ex, Ey, Ed, plotpar)
eldisp2(Ex, Ey, Ed, plotpar, sfac)

Description:

eldisp2 displays the deformed mesh for a two dimensional structure.

Input variables are the coordinate matrices Ex and Ey formed by the function coordxtr, and the element displacements Ed formed by the function extract_ed.

The variable plotpar sets plot parameters for linetype, linecolor and node marker:

plotpar\(= [\, linetype \quad linecolor \quad nodemark \,]\)

where

\(linetype\)		\(linecolor\)		\(nodemark\)
1	solid line	1	black	1	circle
2	dashed line	2	blue	2	asterisk
3	dotted line	3	magenta	0	no mark
		4	red

Default is dashed black lines with circles at nodes.

The scale factor sfac is a scalar that the element displacements are multiplied with to get a suitable geometrical representation. The scale factor is set automatically if it is omitted in the input list.

Limitations:

Supported elements are bar, beam, triangular three node, and quadrilateral four node elements.
