Grid-based surfaces are calculated with the help of measuring points that are closest to the point to be interpolated. Nodes or elements for which insufficient interpolation points were found are not assigned a value; instead, they are averaged over the values of the compensating surfaces. The following extension appears in the input window:

Entering the area interpolation

The number of runs can be varied. This is necessary if either not enough measured values are available or if their distribution is not uniform. Points that have already been interpolated are also taken into account in the next pass.

By activating the "Close regions without values" checkbox, the Gaussian interpolation is integrated into the area interpolation. This is particularly useful when even a large number of passes cannot compensate for the missing measured values. Selecting this option ensures that all points are interpolated. Normally, one pass is sufficient for complete interpolation. This interpolation method can run completely in parallel.
