內(nèi)容摘要：
Many biological and geological problems can be modeled as transport in porous media, e.g., gas and oil extraction from petroleum reservoirs and drug delivery to cancer sites. Moreover, the media could be poroelastic and transport is subdiffusive. In this talk, we present results from our on-going efforts for development of efficient and robust numerical solvers for time-fractional convection-diffusion problems and (linear and nonlinear) poroelasticity problems. We pay special attention to positivity-preserving, local mass conservation, free of Poisson-locking, and positivity.
