Cem mass effect 3 full#

This uses slave-slave information transfer for state variable information and master-slave transfer for forcing data. Parallel processing using OpenMP or MPI is included in COMPAS following the methodology utilized in SHOC.

As such, it retains the full open boundary suite and turbulence closure suite offered by SHOC. While the MPAS-O model is a global model suitable for coupling with atmospheric and sea-ice models for investigation of climate impacts, the model proposed here is aimed for use at the coastal or regional sea scale. Output can either be in equivalent SHOC formats for structured curvilinear grids (including CF1.0 compliance) or the CF UGRID standard. This formulation has the desirable trait of supporting a stationary geostrophic mode. The tangential velocity used in the Coriolis term is formulated according to Thuburn et al, (2009). Similarly, vertical mixing of momentum is identically retained. This implies the barotropic and baroclinic pressure formulation remain the same as SHOC. We retain the ‘z’ or sigma vertical coordinate of SHOC, with associated wetting and drying algorithm in the ‘z’ implementation. In the first instance, backward compatibility with SHOC is maintained by running the finite volume algorithms on the orthogonal curvilinear grids generated by SHOC, using the identical input parameter file. The framework is grid agnostic, such that the solution is valid for any orthogonal mesh. The scheme conserves total energy and potential vorticity, and mass, velocity and potential vorticity evolve in a consistent manner. This framework uses placement of variables on a C grid, and employs the vector invariant approach to solving momentum advection and the Coriolis term. The process of construction of such a model involves generalization of the unstructured coordinate system, and replacement of some of the dynamic core with finite volume equivalent algorithms.īoth the unstructured generalisation and replacement of dynamic core algorithms follow the MPAS-O ( ) framework as described by Ringler et al (2010) and Ringler et al. This essentially results in a new hydrodynamic model, albeit with full backwards compatibility regarding the peripheral infrastructure of the model (core libraries, sediment, BGC, wave libraries, IO, parameter file configuration). In recognition of the superiority of unstructured meshes over orthogonal curvilinear grids in complex coastal environments, it is considered desirable to transition SHOC into a full finite volume code. triangles, squares, hexagons), which would then make it suitable for finite volume algorithms. It is possible to generalize this system to be suitable for any shaped grid (e.g. This is essentially an unstructured coordinate system for curvilinear grids. The EMS hydrodynamic model, SHOC, utilizes a spare coordinate system internally to organize its data.
