Interpolation between points using a COMSOL App

Application ID: 34491


This App will fit a surface through a set of points using Radial Basis Functions and will write out a COMSOL-format file of a smooth NURBS surface that passes through all of the points. The function describing the surface can also be written to a text file. The point data is read in from comma-delimited file and thin-plate spline radial basis functions are used to fit the surface. Up to 5000 points can be used in this demonstration application.

This app is explained in detail in the following blog post: Using Radial Basis Functions for Surface Interpolation.

This application example illustrates applications of this type that would nominally be built using the following products:
