Spline Operator #577

Closed Rombur closed 3 years ago

Rombur commented 4 years ago

I have extracted the equations we need to implement from Stuart's paper: Mesh-free data transfer algorithms for partitioned multiphysics problems: Conservation, accuracy, and parallelism. The equations are in the following file: spline.pdf

Note there were some tricks to get this to scale for the off-diagonal blocks. Also you could apply some of the scaling you guys did in moving least squares which should make the linear solve better condition.
