A scalable variational inequality approach for flow through porous media models with pressure-dependent viscosity
N. K. Mapakshi, J. Chang, K. B. Nakshatrala
Mathematical models for flow through porous media typically enjoy the so-called maximum principles, which place bounds on the pressure field. It is highly desirable to preserve the…
Modeling flow in porous media with double porosity/permeability: A stabilized mixed formulation, error analysis, and numerical solutions
S. H. S. Joodat, K. B. Nakshatrala, R. Ballarini
The flow of incompressible fluids through porous media plays a crucial role in many technological applications such as enhanced oil recovery and geological carbon-dioxide sequestra…
A performance spectrum for parallel computational frameworks that solve PDEs
J. Chang, K. B. Nakshatrala, M. G. Knepley +1
Important computational physics problems are often large-scale in nature, and it is highly desirable to have robust and high performing computational frameworks that can quickly ad…
