Cubed-Sphere Shallow Water Model (A grid)

This is a cubed-sphere shallow water model

Prerequisite

C++ compiler (higher than C++11)
CMake (higher than 3.0.0) (You can create your own Makefile by translating the CMakefile.txt if you don't want to use CMake)
netcdf-cxx4 (hdf5, netcdf-c are needed for netcdf-cxx) [optional]

Clone the project using:

git clone https://github.com/Aaron-Hsieh-0129/Cubed-Sphere-Shallow-Water-Model-A-grid.git

You can change the model settings by changing the macro flags in the ./src/define.hpp and also the configuration object in the ./src/main.cpp. In general, you only need to modify the configuration in ./src/main.cpp. But if you want to change the numerical methods or the running cases, you might need to modify the flags in the ./src/Config.hpp.
You are able to run the model by running the command under the project folder:
```
sh run.sh
```
or you can use your own command by referencing the command in run.sh.

Install netcdf-cxx

It's a little bit complicated to install libraries for C/C++. I will provide a tutorial for installing C/C++ compiler and the libraries in another file. Here, you don't need to have sudo privilege to install anything.
Link the installed libraries.

If you don't need to use PETSc and netcdf, you might need to turn off the link command in CMakeLists.txt.
You need to change the libraries path (netcdf, petsc) to your own path.

Change include path in CMakeLists.txt:

include_directories(
  </path/to/your/netcdf>/include
)

Change library link path:

find_library(libncxxPath netcdf_c++4 "<path to your netcdf_c++4>/lib")
