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), 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
