Time Average and Time Integral
Select a Time Average () or Time Integral () dataset, found under the More Datasets submenu, to compute the time average or time integral of some time-dependent data in another dataset, for example, to compute time averages or time integrals.
Data
Select a Dataset for the data to compute the time average or time integral. To compute the time average or time integral for a dataset with time-dependent data, select times to include in the average or integral from the Time selection list: All (the default) to use all time steps, First to use the first time step only, Last to use the last time step only, From list to select from a list of all time steps, Manual to enter a range of times as indices directly, or select Interpolated to enter Times.
Settings
If desired, clear the Interpolate between stored time steps check box to improve performance by disabling interpolation between stored time steps. If the check box is selected, you can specify the following properties:
Enter a relative tolerance in the Tolerance field (default: 0.001).
In the Minimum interval length field, enter a minimum interval length as a number relative to the length of the time interval (default: 104). The data is evaluated at least at every stored time step regardless of the value of the minimum interval length.
