$\Delta t_{imp}$, $\Delta t_{ascii}$, $\Delta t_{db}$, fragment
nfilter, efilter, entype${}_{res}$, enid${}_{res}$, $N_{res}$

Parameter definition

$\Delta t_{imp}$ Output interval for complete model (.imp-files)
default: $\Delta t_{imp}= t_{term}/100$
$\Delta t_{ascii}$ Output interval for ASCII data (see list of .out-files in General section)
default: $\Delta t_{ascii}=t_{term}/1000$
$\Delta t_{db}$ Output interval for model database and state files. No database or state files will be output if $\Delta t_{db}$ is larger than $t_{term}$ (see TIME)
default: a database file is generated at $t_{term}$
fragment Flag to activate fragment list generation (only applicable when having node splitting activated)
0 $\rightarrow$ no fragment list generation
1 $\rightarrow$ fragment list is written to .imp-database
nfilter Filter for node and discrete particle data that will be written to impetus.imp
0 $\rightarrow$ output all node data
1 $\rightarrow$ output displacements only
2 $\rightarrow$ do not output discrete particles
efilter Filter for element data that will be written to impetus.imp
0 $\rightarrow$ output all element data
1 $\rightarrow$ output effective stress, plastic strain and damage
2 $\rightarrow$ output no element data
entype${}_{res}$ Entity type for state file output. The state file is an ASCII file in command format containing elements, nodes (coordinates and velocities) and contact information. Stresses, strains and state variables are output to a separate binary file.
options: P, PS, ALL
default: no state file
enid${}_{res}$ Entity ID for state file output
$N_{res}$ Number of cyclic alternating files for model database and state file output
options: $1 \leq N_{res} \leq 9$
default: $N_{res}=9$


This command contains output parameters, such as output frequency and filter. The filter is used to reduce the size of the .imp-files.

If defining entype${}_{res}$ and enid${}_{res}$, elements, node coordinates and velocities and the current contact state will be written to the ASCII file impetus_state1.k. All state variables, stresses and strains are written to a binary file impetus_state1.bin. impetus_state1.k and impetus_state1.bin can be read by IMPETUS Afea Solver. Note that impetus_state1.bin is included in a model using the command INCLUDE_BINARY.
