Conformal hexahedral mesh coarsening by agglomeration
Abstract
Reservoir simulation involves to compute dynamic flow of different phases in
a porous medium. The initial state of the reservoir is usually precomputed via
geo-statistics methods, extrapolating measures of the terrain. so, the input
of reservoir simulation is given as a fine mesh containing heterogeneous data
In this paper, we describe an agglomeration strategy, to dynamically
coarsen this fine hex-dominant mesh. The adaptivity
may be driven by physics and/or geometric estimators. Ideally, the coars-
ening should be applied locally in low gradient regions, whereas high gradient
regions keep the fine mesh.
