suntans-general-vertical-coordinate

Introduction

This is a beta version of the original SUNTANS ocean model (https://github.com/zyaj/suntans). The aim of these codes is to combine all the existing features into one version.

The history of the development for different files is recorded in the "/progress" folder. The latest update is the generalized vertical coordinate for the SUNTANS model.

Discretization schemes

Time-steping schemes: theta method, AI2 and AM2 for implicit scheme, AB2, AX2 and AB3 for explicit schemes.

Spacial schemes: 2nd-order central-difference scheme, and momentum advection with TVD schemes.

New Modules


Hybrid grid: Any arbitrary shape of grid cell or hybrid type of grid mesh.

Vegetation drag parameteriztion: Parameterize the drag effects on momentum conservaton due to the existence of vegetation

Subgrid bathymetry and related parameterization: Apply subgrid bathymetry method and Newton iteration to calculate free surface, resolve high-resolution bathymetry data and related parameterization for bottom drag and sediment transport.

Culvert (pressurized flow): Apply the iterative solver of subgrid bathymetry method and integrate the pressurized flow (culvert flow) into one simulations.

Generalized vertical coordinate: A hybrid/grid generalized vertical coordinate for unstructured-grid, nonhydrostatic ocean modeling (The current option is z-level, sigma, isopycnal, variational moving mesh and user-defined function).

Installation suggestion

The following combinations have been tested.

Parallel1: MPICH2+GCC4.9+Parmetis2.0+Triangle Parallel2: OpenMP+GCC4.9+Parmetis2.0+Triangle
