Numerical solution of subsurface moisture transport problems

An algorithm is proposed for solving difference problems of subsurface hydromechanics by the alternating triangular method (ATM). For second, third, and mixed boundary-valued problems of subsurface moisture transport in the elastic regime, we use an improved ATM generalization scheme, which has been tested by the authors in application to the first boundary-value problem. The proposed algorithm can be applied to various problems of subsurface mass transport.Translated from Vychislitel'naya i Prikladnaya Matematika, No. 56, pp. 83–91, 1985.
