1. A method for assessing peripheral nerve stimulation (PNS) for a coil geometry, the method comprising:
retrieving a PNS Huygens' penalty matrix (P-matrix) for a body model, the PNS Huygens' P-matrix defined on a Huygens' surface enclosing the body model;
generating a coil specific PNS P-matrix for the coil geometry based on at least the PNS Huygens' P-matrix for the body model;
determining at least one PNS threshold for the coil geometry based on the coil specific PNS P-matrix;
storing the at least one PNS threshold in a storage device;
determining an adjustment of one or more of a parameter of or position of the coil geometry based on the at least one PNS threshold for the coil geometry; and
adjusting the one or more of a parameter or a position of the coil geometry based on the determined adjustment.
