Effective Numerical Methods for Multiscale Heterogeneous Problems in Geophysics

The speakers will present some effective numerical methods to capture correctly large scale solutions for flows through highly heterogeneous media. A central idea is to introduce multiscale finite elements which are adapted to the local microstructures of the flow. Thus, the effect of small scale information on the large scale is properly taken into account. The methods presented by the speakers apply to general multiscale problems without restricive assumptions on scale separation and periodicity.
