The input record contains two fields;

gradient #rows #columns { d_11 d_12 ... ; d_21 ... } (required)
cCoords #columns x_1 x_2 ... (optional, default 0) The prescribed gradients columns must be equal to the size of the center coordinates. The size of the center coordinates must be equal to the size of the coordinates in the applied nodes.
