Composable block solvers for the four-field double porosity/permeability model
M. S. Joshaghani, J. Chang, K. B. Nakshatrala +1
The objective of this paper is twofold. First, we propose two composable block solver methodologies to solve the discrete systems that arise from finite element discretizations of…

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…

Variational inequality approach to enforce the non-negative constraint for advection-diffusion equations
J. Chang, K. B. Nakshatrala
Predictive simulations are crucial for the success of many subsurface applications, and it is highly desirable to obtain accurate non-negative solutions for transport equations in…
