Interpolation
Once the target node has been located, and mapped onto old grid element local
coordinates x and h, the interpolated values of p, q, and h are found using the following
equations:
n
h = ∑ φi hi
(E7)
i=1
n
p = ∑ φi pi
(E8)
i=1
n
q = ∑ φi qi
(E9)
i=1
where n is the number of nodes on the old grid element and f is the appropriate
interpolation function.
