Enhanced Interpolation routine that prevent .csv files to be interpolated onto a large mesh. Previously you could run this routine in parallel but it would read all fo the .csv file on every partition and thereby run out of memory. In this updated feature we check the size of the partitioned domain and only read the points in the .csv file that overlap with the local domain. Also dded test to ensure it works as advertised.
