-There are two methods for querying the interpolant field:
-
-sInterp - takes a single Cartesian coordinate.
-rInterp - takes a range of Cartesian coordinates as an array. The first 3 columns are assumed to be the x,y,z coordinates. Further columns can be present e.g. velocity components - these are ignored.
+To query the interpolant field call the "Query" method. Input can be a single set of Cartesian coordinates x,y,z or a range of points as an array.
+If a range, the first 3 columns are assumed to be the x,y,z coordinates. Further columns can be present e.g. velocity components - these are ignored.
