Description

DVcell_to_node converts Cell_Data to Node_Data. It is necessary to visualize cell-based data when the visualization macro or base module selected does not process cell-based data.

Note: All nodes referenced by a cell with a NULL value will have their Node_Data set to NULL.

Inputs

&in

A reference to a field containing any type of Mesh and also Cell_Data.

comps[]

An integer array of variable length that specifies which components (0-n) of the input Cell_Data to convert to Node_Data. As many components will be converted as the length of this array. If the Cell_Data contains multiple cell_sets, then the conversion is performed on the specified components in each cell_set.

This array is generally provided by a combination of UIoptionBoxLabel and DVcell_data_labels.

order

An integer that sets the order of interpolation. Allowed values are:

averaging. A node's value is computed by averaging values at all adjoining cells.

1-n

A node's value is computed by interpolating values using distances from the node to the adjoining cell centroids.

Output

&out

The output is a reference to a merged object that contains the new Node_Data, plus the existing Mesh and Cell_Data.
