If you want a simple linear interpolation, using MapFieldDataFromSourseToDestination, or MapFieldDataOntoNodes should work, but you will need connections for the original points (a surface or volume mesh).  you can create a volume mesh from a point cloud using IterfaceWithTetgen and disabling the PLC option, which will create a mesh of the convex hull of the points.

If you need other than linear interpolation, there is some support for laplacian interpolation using the BuildFEMatrix module.  This is a bit more complicated, but if you need more details I can explain it in another email. 

cheers,
Jess

I use this all the time.

We have a mesh of the atria and a number of data points on that surface.  We would like to interpolate between those data points on that surface.

Is this something that Sci-run can do?

Thanks
