# MapFieldDataOntoNodes This module maps data from one mesh or point cloud to another mesh or point cloud. The output mesh will have the data located at the nodes. **Detailed Description** This modules can interpolate a scalar field, or calculate and interpolate the gradient, gradientnorm, or flux. The first input is the **source** field. The second input allows you to specify the **weights** of the interpolation. The output is the **target** field containing the interpolated data on the elements.
