eliso2¶

Purpose:

Display element iso lines for two dimensional elements.

Syntax:

eliso2(Ex, Ey, Ed, isov)
eliso2(Ex, Ey, Ed, isov, plotpar)

Description:

eliso2 displays element iso lines for a number of elements of the same type. Note that only the iso lines are displayed. To display the element mesh, use eldraw2.

Input variables are the coordinate matrices Ex and Ey formed by the function coordxtr, and the element nodal quantities (e.g., displacement or energy potential) matrix Ed defined in extract.

If isov is a scalar, it determines the number of iso lines to be displayed. If isov is a vector, it determines the values of the iso lines to be displayed (number of iso lines equal to the length of vector isov):

isov\(= [\, \text{iso lines} \,]\)

isov\(= [\, \text{isovalue}(1) \; \ldots \; \text{isovalue}(n) \,]\)

The variable plotpar sets plot parameters for the iso lines:

plotpar\(= [\, linetype \;\; linecolor \;\; textfcn \,]\)

where

\(linetype\)		\(linecolor\)		\(textfcn\)
1	solid line	1	black	0	iso values not printed
2	dashed line	2	blue	1	iso values printed at the iso lines
3	dotted line	3	magenta	1	iso values printed where the cursor indicates
		4	red

Default is solid, black lines and no iso values printed.

Limitations:

Supported elements are triangular 3 node and quadrilateral 4 node elements.
