## Group Bomhof

Group Description |
Matrices from circuit simulation problems. Wim Bomhof, Univ. Utrecht. Modelled as a system of differential algebraic equations. Normally solved with a BDF method, and Newton's method, which give rise to linear systems that need to be solved. A, x, and b are provided. Wim Bomhof, Univ. Utrecht (now at PLAXIS (www.plaxis.nl), a small company that develops a finite element code for geomechanical problems. email: (first name in lower case).(current directory name in lower case) at hetnet.nl. circuit matrices posted at http://www.math.uu.nl/people/bomhof/. Added to the UF sparse matrix collection in December 2001. Citations: Wim Bomhof and Henk van der Vorst, A parallel linear system solver for circuit simulation problems. Numer.
