Writing Problem Generators and Parsing Input

Documentation/ProgrammerGuide/Problems and Input

Perhaps the most common task for new users of Athena is writing new problem generator functions.

A large number of examples of problem generators can be found in src/prob and athena/apps directories.

Further instructions on how to write problem generators, and how to use functions in the parser (athena/src/par.c) to read input from the input file can be found in this User Guide section
