Description

DVinterp_cell_data uses the node coordinates specified in the input mesh (in_probe) as a set of sample points for the in_field. For each sample point, it locates the cell containing that point in the in_field, and uses the (possibly vector) value of the given component in that cell as the node data in the output field. If there is no cell in in_field containing a given sample point, a null data value is used.

Input

in

Mesh+Cell_Data. This field is sampled at the locations determined by the nodes of the probe mesh.

probe

Mesh. The node coordinates of this field define the sample points for interpolating the input field.

component

int. Which data component to interpolate.

Output

out

The interpolated output field.

Example

Not available.
