[GiDlist] Postprocessing - Interpolation

Kendon_Tim · March 14, 2002, 9:47am

Hello there!

Does GID have the capabalilities to interpolate a set of values associated
with a set of scattered data points to a generated mesh?

In a typical numerical work this might be done by Delauney triangularization
of the scattered data points (2D problem) and then local interpolation
within each triangular to the vertices of the mesh.

Can anyone help with this request??

Alternatively can GID mesh through a set of scattered data points? Seems to
me I need at least lines to mesh.

Many thanks

Internally, GiD can create a Delaunay mesh or triangles from a set or points
(2D or 3D projected in 2D), but this capability is not public.

You can use some program as “Surfer” (www.goldensoftware.com) for your
pourposes.

You can use the “triangle” software, is free and with code.
