A Finite Element Program (FECGS): Post-Processor FEPOST - GKSS

3.1. *CONTOUR: DRAWING CONTOUR PLOTS 15
3.1.2 *HISTORY: Selecting time increments
*HISTORY, suboption of *CONTOUR, is used to specify the time increments to be plotted.
By default, all the time increments recorded are plotted.
Format Entry
The following data lines are needed if the *HISTORY suboption is used:
For step increment base
A, 3I ”STEP” K, INC1, INC2. ”STEP” is case sensitive. K - Step number,
INC1 - first incremental number, INC2 - last incremental number.
FEPOST draws all the increments between INC1 and INC2 at step K.
or, in crack extension base
A, I, nF ”Da” n, Da 1, Da 2, . . . , Da n. Here, ”Da” is case sensitive, n is number
crack extension to be selected, Da i is ith selected crack extension.
Examples:
1. Use the following entries to draw contour plot in the corresponding time increments: step 1
all increments within increments 5 and 100; step 2 increment 50; and step 3 increment 100.
*HISTORY
STEP 1, 5 100
STEP 2, 50 50
STEP 3, 100 100
2. Use the following entries to draw contour plot for the time increment corresponding to the
crack extensions at, or about at 0.0, 1.0, 2.0, 4.0 and 6.0.
*HISTORY
Da 5, 0.0, 1.0, 2.0, 4.0, 6.0
