#Example_c2 Solving for potential in the skull

            #This example solves for the potential on the surface of
            #the skull due to an arbitrary dipole placed inside the
            #skull.  Note that this problem requires a large parameter
            #set for CMISS. A suitable parameters.inc file is given in
            #the example directory for this example.

#Calculate the potential on the skull

fem export node;skull_geometry as full_skull
fem export node;skull_potential as full_skull field #Export the
