P047 EXTENDING THE LIMITS OF RESISTIVITY MODELLING USING MULTIGRID TECHNIQUES Abstract 1 We present an adaptation of the multigrid algorithm application to the solution of the DC resistivity modelling problem in geophysics. Previous work on multigrid solvers in this application (e.g. Cheesman and Bailey 1996) has shown that multigrid is fast but probably not significantly faster than other good solvers that have been implemented such as biconjugate gradient (Mackie et. al. 1995). The potential importance of multigrid solvers does not however lie in their speed at forward modelling but in their potential for inverse modelling. Inverse solvers which proceed by
