We investigate these aspects, using a local model parameterization in the form of a tetrahedral grid with linear interpolation in between grid nodes.
In this paper, WENO schemes (e.g. Advanced Numerical Approximations of Nonlinear Hyperbolic Equations, Lecture Notes in Mathematics, vol. 1697, Springer, Berlin, 1998, pp. 325 432) are used for the convection terms and a local grid adaptation technique is presented that uses the smoothness indicators and interpolation polynomials of the WENO schemes.
A local grid adaptation technique is used to increase the grid density where required.
The local model was run independently from the regional model using time-varying specified heads for the lateral boundaries that were previously computed by a coupled regional-local model simulation using the local grid refinement method of MODFLOW-LGR2 (Mehl and Hill 2013).
Despite the cloud features, the evaluation reported was performed on a local, grid-like cluster.
However, the option of using local grid refinement to embed the fractures is computationally expensive as well as intrusive to a reservoir model.
First, the standard way of calculating offset emissions uses the local grid in Massachusetts rather than the one in North Carolina as a point of reference — even though the emissions that are actually being displaced are those of the much more coal-dependent southern grid.
We locate these 50 events with grid search over possible local source locations using a coarse grid size of 1 × 1 km.
One possible solution to the computational bottleneck during high volume periods might be to temporarily deploy more computing nodes, either on the local network, or using a computing grid solution.
Using a regular grid of solution points, the method incorporates this law in terms of a local autoregressive average with coefficients depending on the distance between solution points.
