     * element within the element block is specified in the input file (and optionally perturbed). An approximation
     * of the load vector is obtained by accumulating the resulting (possibly perturbed) value into the nodes. Then,
     * a lumped version of the mass matrix is inverted and used to solve for the approximate nodal point initial
     * conditions.
