RUNNING_AVERAGE_OUTPUT

Specifies nodal output parameters for running average fields.

AcuSolve Command

Syntax

RUNNING_AVERAGE_OUTPUT {parameters}

Qualifier

This command has no qualifier.

Parameters

output_frequency or out_freq (real) >=0 [=0]
Time step frequency at which to output nodal running average fields. If zero, this option is ignored.
output_time_interval or out_intv (real) >=0 [=0]
Time frequency at which to output nodal running average fields. If zero, this option is ignored.
num_saved_states or save (integer) >=0 [=0]
Number of nodal running average field files to keep. If zero, all are kept.

Description

This command specifies the frequency at which nodal running average fields are written into a results database on disk. Running average fields are output only if they are defined by the EQUATION command. For example,
RUNNING_AVERAGE_OUTPUT {
output_frequency      = 10
output_time_interval  = 2.5
}

specifies that the nodal running average fields are to be output at every 10 time steps, at every 2.5 units of run time and at the last time step.

Once the nodal running average fields have been written to disk, they can be translated to other formats using the AcuTrans program and other post-processing modules; see the AcuSolve Programs Reference Manual for details.

If either output_frequency or output_time_interval is non-zero, the nodal running average fields will be output at the end of the run. If both are zero, no data are written to disk.

Run times may not coincide with output_time_interval. In this case, at every time step which passes through a multiple of output_time_interval, the nodal running average fields are output.

The num_saved_states parameter indicates the number of nodal running average field files to save. Once the (num_saved_states + 1)th file is written, the first one is removed. When running in parallel, once all files are written (in parallel), then the old ones are removed (in parallel).
