# ATC: fix_modify AtC output

# fix_modify AtC output

## syntax

fix_modify AtC output <filename_prefix> <frequency> [text | full_text | binary | vector_components | tensor_components ] fix_modify AtC output index [step | time ]

- filename_prefix (string) = prefix for data files
- frequency (integer) = frequency of output in time-steps
- options (keyword/s):
  text = creates text output of index, step and nodal variable values for unique nodes
  full_text = creates text output index, nodal id, step, nodal coordinates and nodal variable values for unique and image nodes
  binary = creates binary Ensight output
  vector_components = outputs vectors as scalar components
  tensor_components = outputs tensor as scalar components (use this for Paraview)

## examples

`fix_modify AtC output heatFE 100`
`fix_modify AtC output hardyFE 1 text tensor_components`
`fix_modify AtC output hardyFE 10 text binary tensor_components`
`fix_modify AtC output index step`

## description

Creates text and/or binary (Ensight, "gold" format) output of nodal/mesh data which is transfer/physics specific. Output indexed by step or time is possible.

## restrictions

## related

see fix atc command

## default

no default format output indexed by time
