For transfers of intensive data between like topologies when the source data is on element centroids, element-based versions of the Radial Basis Function (RBF) mapping algorithm may be used to generate data on overlapping target locations.
Two versions of the source element RBF algorithm are available: one for volumes and one for surfaces. Details for each are shown in Table 1: Source element RBF algorithm versions.
The following beta features are available:

Revert to Node-Based RBF Mapping for Volumes
For volume-to-volume transfers of intensive data with the source points on element centroids, System Coupling uses the source-element Radial Basis Function (RBF) mapping algorithm by default.
To revert to the node-based RBF algorithm—which reconstructs elemental data on element nodes and then performs mapping on the reconstructed data—set the AnalysisControl.AvoidDataReconstruction.VolumeMapping beta setting to False.
Use Source-Element RBF Mapping for Surfaces
To use the element-based RBF algorithm for surface-to-surface mapping, set the AnalysisControl.AvoidDataReconstruction.Surface beta setting to True.
