Detailed Description

This module provides some subroutines to create a typical physical field, such as solid body rotation.

About Field_Pattern_Builder module

By the subroutines in this module, one can create the physical fields commonly used for numerical simulation in geophysical fluid dynamics, such as solid body rotation, planetary vorticity or cosin bell field.
The created physical field data will be stored in derived type Field_IcGrid2D which manages a physical field on icosahedral grid.
