Elliptic differential operators describe a wide range of processes in mechanics relevant to geo-energy applications. Extensively used reservoir modeling, the Finite Volume Method with TPFA can be consistently applied discretize only specific type application under severe assumptions. In this paper, we introduce positivity preserving Nonlinear Two Point Stress Approximation (NTPSA) based on rece...

We develop a new way to calculate the overlap of boundary state with finite volume bulk in truncated conformal space approach. check this method thermally perturbed Ising model analytically, while scaling Lee-Yang numerically by comparing our results excited g-functions, which we obtained analytical continuation method. also give simple argument for structure asymptotic between and periodic mul...
