12.2 Execution Report

An execution report is written to standard output (generally somewhere on screen) and furthermore to <name>.protocol.txt. This starts with general information which should be self-explanatory.

Following lines report about every iteration of every computed instant of time of every simulation step. This has the following data

iter

with

	step counter starting with 0
	instant of timne value within current step
	target time for current step
	actual time for current step
	iteration counter for current
	the first -iteration is performed with the displacement state of the last (hopefully converged) iteration of the preceding instant of time
	this serves to control system state changes due to state changes of material models
	equilibrium residual for current iteration
	ratio of current residual energy to initial residual energy
	residual energy is the vector product of residual vector with displacement increment – related to preceding iteration – current iteration
	the initial residual energy is computed with iteration
	computed arc length – euclidean vector norm – of current nodal displacement increment vector
	current nodal displacement increment vector is the difference relating to preceding instant of time and the actual iteration of actual instant of time

Regular report lines are interrupted by messages about results written to files.
Regular report lines may further be interrupted by messages about state changes regarding certain types of material models.
