Description of components

By default the value of the calculated quantity can be referenced elsewhere in the input file by using the label of the action. Alternatively this Action can be used to calculate the following quantities by employing the keywords listed below. These quantities can be referenced elsewhere in the input by using this Action's label followed by a dot and the name of the quantity required from the list below.

Quantity	Description
.#!value	the time series for the input quantity

Compulsory keywords

ARG	the label of the value whose time series is being stored for later analysis
STRIDE	( default=1 ) the frequency with which the data should be collected and added to the quantity being averaged
CLEAR	( default=0 ) the frequency with which to clear all the accumulated data. The default value of 0 implies that all the data will be used and that the grid will never be cleared
TYPE	( default=auto ) required if you are collecting an object with rank>0. Should be vector/matrix and determines how data is stored. If rank==0 then data has to be stored as a vector

Options

NUMERICAL_DERIVATIVES

( default=off ) calculate the derivatives for these quantities numerically

UPDATE_FROM

Only update this action from this time

UPDATE_UNTIL

Only update this action until this time
