Hi,
a) in version 6.0 ContourPlot[] will work with data in any position
as to see from
ListContourPlot[Table[Random[], {5}, {3}]]
b) and for higer finite elements you have to write the correct
interpolation routine. But it may be sufficient, to
compute the function on a triangular mesh and feed it into
ListContourPlot[]
Regards
Jens
