Trying to interpolate rather huge 3D unstructured grid of ~200k nodes using:
Interpolation[Table, InterpolationOrder -> 1]
At first execution works well, but then gives errors:
TetGenTetrahedralize::err: Tetrahedralize returned an error. >>
TetGenDelaunay::tetinst: A TetGen instance could not be created. >>
Interpolation::umesh: Unable to find a mesh from the points {{-0.12181,-0.02508,0.},<<191977>>} for interpolation. >>
Kernel restart solves problem, but I just cannot read input data files each time.
May be RAM memory issue, not sure, not an expert on this.
(MathKernel gets 1.5Gb RAM, whereas more than 40Gb are free).
Any ideas? Thanks.
