Adaptive multilevel space-time-stepping scheme for transport in heterogeneous porous media (ADM-LTS)Carciopolo, Ludovica Delpopolo (author), Cusini, Matteo (author), Formaggia, Luca (author), Hajibeygi, H. (author)We present ADM-LTS, an adaptive multilevel space-time-stepping scheme for transport in heterogeneous porous media. At each time step, firstly, the flow (pressure) solution is obtained. Then, the transport equation is solved using the ADM-LTS method, which consists of two stages. In the first stage, an initial solution is obtained by imposing the...journal article 2020

Hosseinimehr, S.M. (author), Arbarim, Rhadityo (author), Cusini, M. (author), Vuik, Cornelis (author), Hajibeygi, H. (author)A dynamic multilevel method for fully-coupled simulation of flow and heat transfer in heterogeneous and fractured geothermal reservoirs is presented (FG-ADM). The FG-ADM develops an advanced simulation method which maintains its efficiency when scaled up to field-scale applications, at the same time, it remains accurate in presence of complex...conference paper 2019

Hosseinimehr, S.M. (author), Cusini, M. (author), Vuik, Cornelis (author), Hajibeygi, H. (author)We present an algebraic dynamic multilevel method for multiphase flow in heterogeneous fractured porous media (F-ADM), where fractures are resolved at fine scale with an embedded discrete modelling approach. This fine-scale discrete system employs independent fine-scale computational grids for heterogeneous matrix and discrete fractures,...journal article 2018

Hosseinimehr, S.M. (author), Arbarim, R.B. (author), Cusini, M. (author), Vuik, Cornelis (author), Hajibeygi, H. (author)Accurate numerical simulation of coupled fluid flow and heat transfer in heterogeneous geothermal reservoirs demand for high resolution computational grids. The resulting fine-scale discrete systems--though crucial for accurate predictions--are typically upscaled to lower resolution systems due to computational efficiency concerns. Therefore,...conference paper 2018

Cusini, M. (author), Gielisse, Robin (author), Groot, Hans (author), van Kruijsdijk, C.P.J.W. (author), Hajibeygi, H. (author)Field-scale simulation of flow in porous media in presence of incomplete mixing demands for high-resolution computational grids, much beyond the scope of state-of-the-art simulators. Hence, the upscaling-based Todd and Longstaff (TL) approach is typically used, where coarse grid cells are employed with effective mixing fluid properties and...journal article 2018

Cusini, M. (author), van Kruijsdijk, C.P.J.W. (author), Hajibeygi, H. (author)An algebraic dynamic multilevel method (ADM) is developed for fully-implicit (FIM) simulations of multiphase flow in heterogeneous porous media with strong non-linear physics. The fine-scale resolution is defined based on the heterogeneous geological one. Then, ADM constructs a space-time adaptive FIM system on a...conference paper 2016

Cusini, M. (author), Lukyanov, A. (author), Natvig, J. (author), Hajibeygi, H. (author)Unconventional Reservoir simulations involve several challenges not only arising from geological heterogeneities, but also from strong nonlinear physical coupling terms. All exiting upscaling and multiscale methods rely on a classical sequential formulation to treat the coupling between the nonlinear flow-transport equations. Unfortunately, the...conference paper 2014
