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 selfexplanatory.
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.
