# fix_modify AtC output command

## Syntax

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

- AtC fixID = ID of fix atc instance

- output or output index = name of the AtC sub-command

- filename_prefix = prefix for data files (for output)

- frequency = frequency of output in timesteps (for output)

- optional keywords for output:

  - 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 (for use with ParaView)

- step or time = index output by step or by time (for output index)

## 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 indexing by step or time is possible.

## Restrictions

None.
