+FastCap is a three-dimensional capacitance extraction program.
+
+FastCap computes self and mutual capacitances between ideal
+conductors of arbitrary shapes, orientations and sizes.
+The conductors can be embedded in a dielectric region composed
+of any number of constant-permittivity regions of any shape and
+size.
+
+The algorithm used in FastCap is an acceleration of the
+boundary-element technique for solving the integral equation
+associated with the multiple-conductor, multiple-dielectric
+capacitance extraction problem. The linear system resulting
+from the boundary-element discretization is solved using a
+generalized conjugate residual algorithm with a fast multipole
+algorithm to efficiently compute the iterates.
