Fastcap
Jul 20, 2023
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.
This version of fastcap has been cleaned up and enhanced by Stephen R. Whiteley of Whitleley Research Inc. ———————
