Abstract
-- High performance parallel pseudo-spectral methods for the simulation of two-dimensional miscible displacements in porous media are developed. The code is designed to perform high resolution, space and time accurate simulations of nonlinear viscous finger interactions, on var- ious distributed memory architectures. The parallelization is based on a domain decomposition approach in latu sensu, where the decomposition is done either in physical space or in the Fourier representation of the fields. Simulations show occurrence of finger interaction mechanisms on isotropic and Taylor dispersion cases, and stresses the importance of the initial conditions even for results of long time integrations
