CJUMP

CJUMP, Option, Input1, Input2, Input3, Input4, Input5, Input6, Input7, Input8
Initiates a cycle-jump analysis.

SOLUTION: Analysis Options

Option

Option to be applied:

CRIT	—	Jump criterion.
INTENT	—	Declaration of cycle jump analysis intent. For an analysis that begins with a standard solution, specify before the first SOLVE command.
MINCYC	—	Minimum number of cycles before a jump is allowed (and, if desired, the empirical adjustment of minimum intermediate cycles).
INICYC	—	Minimum number of initial cycles before a jump is allowed.
MAXJUMP	—	Maximum allowable jump.
RELTIME	—	Relative time.
CONTROL	—	Control-variable selection.
CNMT	—	Material-ID-dependent jump control.
ADCR	—	Material-ID- and/or control-variable-dependent jump criteria.
CALC	—	Jump-calculation option.
PERC	—	Statistical-jump calculation.
OUTP	—	Diagnostic information output.

Input1

Additional input according to the specified Option:

`Option`	`Input1 =`	`Input2` =	`Input3`, …, `Input8` =
CRIT	Value of jump criterion.	---	---
INTENT	---	---	---
MINCYC	Minimum number of cycles. Default = 3.	Increase of minimum intermediate cycles. Default = 0.	Decrease of minimum intermediate cycles. Default = 0.
INICYC	Initial number of cycles. Default = 3.	---	---
MAXJUMP	Maximum allowable number of cycles to jump. No default.	---	---
RELTIME	Relative time. Default = time value corresponding to the absolute maximum load for a defined load cycle.	---	---
CONTROL	S – Stress (default).	---	---
	EPPL – Plastic strain.	---	---
	DOF – Degrees of freedom.	---	---
	SVAR – State variables.	MAT	`Input3` = Material ID
	SVAR – State variables.	SEL	`Input3`,…,`Input8` = State variable values assigned to six locations.
CNMT	`Input1`,`Input2`,…,`Input6` = Material ID values assigned to six locations.
ADCR	MAT - Material.	Material ID.	Jump-criterion value.
ADCR	CONT - Control variable.	Control-variable label.	Jump-criterion value.
CALC	1 - Slope-based jump calculation (default).	---	---
CALC	2 -Variable-based jump calculation.	---	---
PERC	Percentile value of the cumulative frequency.
OUTP	---	---	---

Command Default

Cycle jump analysis is disabled.

Notes

When Option = CONTROL, any input of a control variable replaces the default (S). If stress is also needed in combination with another control variable (or variables), you must specify it explicitly.

CJUMP requires a corresponding cyclic loading analysis (CLOAD).

For more information, see Cycle-Jump Analysis in the Advanced Analysis Guide.

This command is also valid in PREP7 (/PREP7).
