averaging:elemental to nodal (fields container)

Version: 0.0.0

Description

Transforms Elemental Nodal fields to Nodal fields. The result is computed on a given node's scoping.1. For a finite element mesh, the value on a node is the average of the values of the neighbour elements.

  1. For a finite volume mesh, the agorithm is :
    • For each node, compute interpolation weights for the cells connected to it based on the Frink's Laplacian method.
    • If the determinant of the I matrix is zero, switch to an inverse distance weighted average.
    • If not, compute the Frink weights and apply the Holmes' weight clip.
    • If the clipping produces a large overshoot, inverse volume weighted average is used..
  2. For a face finite volume mesh inverse distance weighted average is used.
