Basics
In this chapter, we present the basics of AMReX. The implementation source
codes are in amrex/Src/Base/. Note that AMReX classes and functions are in
namespace amrex. For clarity, we usually drop amrex:: in the example
codes here. It is also assumed that headers have been properly included. We
recommend you study the tutorial in
amrex-tutorials/ExampleCodes/Basic/HeatEquation_EX1_C while reading this chapter. After
reading this chapter, one should be able to develop single-level parallel codes
using AMReX. It should also be noted that this is not a comprehensive reference
manual.
