Finite Volume and Mixed Finite Element Methods in Geoscience Applications

Geophysical applications require the development of numerical methods that are conservative, compute fluxes accurately, work on general meshes, and on equations with discontinuous tensor coefficients. Finite volume methods are conservative and work for discontinuous coefficients, but are difficult to generalize for distorted meshes and tensor coefficients. Mixed finite element methods are conservative and work for tensor coefficients, but are not well defined on distorted meshes. The speakers will discuss theoretical and computational aspects of FV and MFE methods.
