Description
Summary
The BuildMatrixOfSurfaceNormals calculates area weighted normal vectors per node.
Detailed Description
For each node in the input surface mesh, find the attached faces, and average the face normal weighted by area for that node. Output a nx3 DenseMatrix where n is the number of nodes in the input surface mesh. This matrix can be passed to SwapFieldDataWithMatrixEntries to map this data back to a vector field with the same mesh.
