Add a Filter (
) node from the
Datasets menu to create a dataset that filters data from another dataset using a lower or upper bound or both a lower and an upper bound. You also specify the expression that specify what part of the data that you want to filter.
Click the Plot button (
) to visualize the filter dataset in a plot.
From the Dataset list, select a dataset that contains the data that you want to filter.
From the Bounds list, choose the bounds for the filtering of the expression:
Lower (the default),
Upper, or
Lower and upper. Depending on the chosen bounds, enter values for the bounds in the
Lower bound and
Upper bound fields.
Select a Geometry level:
Taken from dataset (the default),
Volume,
Surface,
Line, or
Point. The default means the highest geometry dimension for the data in the dataset: typically volumes in 3D, surfaces in 2D, and lines in 1D. Select the
Propagate to lower dimensions check box to make a geometry level of volumes, for example, also include their adjacent surfaces, lines, and points.
Select a data Smoothing method —
None,
Inside material domains (the default, for smoothing within domains shared by the same material but not across material boundaries),
Inside geometry domains (for smoothing within each geometry domain but not across interior boundaries),
Everywhere, or
Expression. If you choose
Expression, enter an expression in the
Expression field such that smoothing occurs where the expression is continuous. The default expression is
dom, the domain variable, which is equivalent to the
Internal smoothing. You can also — in a surface plot, for example — use
material.domain, which is an indicator variable for domains that share the same material (see
Material Group Indicator Variables) and is equivalent to the
Inside material domains setting. For all
Smoothing methods except
None, you can also choose smoothing threshold, if needed. From the
Smoothing threshold list, select
None (the default), or select
Manual to enter a relative smoothing threshold value (default: 0.1) in the
Threshold field. The
Use derivatives check box controls whether cubic (Hermite) interpolation is used when applying the filter and is selected by default.
