Hi, I posted this question a couple of days ago but did not get any response. Meanwhile I noticed that the Save-d interpolation data contains "NDSolve`FEM`ElementMesh", which may relates to my problem. Let me restate the question. I have 2D unstructured data in the form {{{1.22001, 0.00024605}, 0.816237}, {{1.22334, 0.000250332},0.436219},... } (connectivity is also available but I do not know how to use it with Mathematica). Interpolation issues a warning: "Interpolation::udeg: Interpolation on unstructured grids is currently only supported for InterpolationOrder->1 or InterpolationOrder->All. Order will be reduced to 1. >>", The warning is not an issue for me, the problem is that I cannot use Save/Get for this interpolation function. After Get the interpolation function instead of a number returns: intp[1., .8] InterpolatingFunction[{{0.000905256237704326, 1.9993734385285347}, {0.00024605021944692736, 0.9989678166248219}}, {4, 4225, 0, {10880, 2}, {2, 2}, 0, 0, 0, 0, Automatic}, {NDSolve`FEM`ElementMesh[{{1.220009724772626, 0.00024605021944692736}, {1.223336731504134, 0.0002503318707254048}, {1.2273720422942693, ... which is the non-evaluated content of the Save-d file. What is the right way to use Save/Get for interpolation of unstructured data? Any help will be highly appreciated. Thanks, --Ted
