for massively parrallel you can use the keyword:
Bounding Box dx = Real XX
Only data points that are within Max/Min mesh corrdinates (of the current partition) + the real Value XX will be transfered to the interpolation library ((Default) no bounding box);
This could become problematic with very large data files; but usually this solver is used only once for initialisation.
compilation of the ScatteredDataInterpolator and Griddatareader can now be done automatically with cmake if you provide paths to the required library.
cf e.g. http://elmerice.elmerfem.org/wiki/doku. ... :scattered
