interpolate data
The interpolate data module interpolates nodal and/or cell data from a 3D or 2D field to either a 2D mesh or 1D line. Typical uses of this module are mapping of data from a 3D mesh onto a geologic surface or a 2D fence section. In these applications the 2D surface(s) simply provide the new geometry (mesh) onto which the adjacent nodal values are interpolated. The primary requirement is that the data be equal or higher dimensionality than the mesh to be interpolated onto. For instance, if the user has a 2D surface with nodal data (perhaps z values), then a 1D line may be input and the nearest nodal values from the 2D surface will be interpolated onto it.
This module supplants the deprecated interpolate nodal data and interpolate cell data modules.

Properties
| Property | Type | Description |
|---|---|---|
| Allow Run | Boolean | This toggle can prevent the module from running. Allowing the user to make changes to large data sets without waiting for updates. |
| Execute | Button | If Allow Run is turned off the Execute button will force the module to run once with the current settings. |
| Method | Choice: Accurate, Nearest Neighbor | The Method option controls how the closest cell to a point or cell is determined. The Nearest Neighbor option finds closest cells by using distances to cell nodes to interpolate node data and cell centers to interpolate cell data. This method is fast but may not select the accurate neighbor in all cases and also cannot reject nodes and cells outside the volume. The Accurate option finds the cell containing a point within its bounds and uses its nodes to interpolate node data and the cell itself to interpolate cell data. This method is slower but will yield accurate results. |
| Remove Nodes Outside Volume | Boolean | The Remove Nodes Outside Volume control tells the algorithm what to do with nodes or cells from the Input Destination Field that fall outside of the coordinate range of the Input Data Field. |
| Node Data To Interpolate | Multi-select | The Node Data To Interpolate control is used to select which scalar nodal data component is to be interpolated onto the surface or line of interest. |
| Node Data To Include | Multi-select | The Node Data To Include control lists all of the node data from the Input Destination Field that can be included in the output. This data will occur after the interpolated data in the field. |
| Cell Data To Interpolate | Multi-select | The Cell Data To Interpolate control is used to select which scalar cell data component is to be interpolated onto the surface or line of interest. |
| Cell Data To Include | Multi-select | The Cell Data To Include control is used to select which scalar data component is to be interpolated onto the surface or line of interest. |
