PRIMER 22.1

Example Use of INTERPOLATE (Search Distance Mode)

Distance = 0
In this figure two nodes in the centre of a flat plate have been raised, with no INTERPOLATE value set.
It is clear that only they have moved, and adjacent nodes are unaffected.

Distance = 20, Order = 1.0
In this figure the same nodes have been moved, but now INTERPOLATE has been switched on. The Distance chosen is equal to half the smaller mesh dimension.
Here Order = 1.0, so there is a linear interpolation between the selected nodes and the edge of the mesh.

Distance = 20, Order = 0.5
In this final figure the Order value has been reset to 0.5, giving a curved variation from centre to edge of the mesh.
This shows how a non-linear effect can be achieved.
