PFLOTRAN input deckΒΆ

A PFLOTRAN input data is organized into blocks, for example the computational grid, the properties of water, etc. The contents of a block can be entered over a single or multiple lines. Each block starts with a keyword, and in case of a multiple-line blocks, is terminated by the keyword END or /. Although PFLOTRAN input is generally case-independent in this case an upper-case END is required. An input block can include one or more sub-blocks.

The following example is a block which defines the simulation time and time stepping:

TIME
  FINAL_TIME 1000 d
  INITIAL_TIMESTEP_SIZE 0.01 d
  MINIMUM_TIMESTEP_SIZE 1.0D-10 d
  MAXIMUM_TIMESTEP_SIZE 50.d0 d
END

The exclamation mark !, and the hash sign # introduce a comment: when one of them is encountered at the beginning or somewhere else in a line, anything that comes after it will be ignored.

It is a good practice to use indentation when including sub-blocks, as in the TIME example above. Although this makes the input dataset more readable, it is not compulsory.

There is also a keyword index available for direct reference.
