ASCII1D format

``ASCII1D'' is a simple data format for small 1D problems. Each line of the data file is coded in ascii and can be easily edited, or produced by programs, or both.

A line begining with the # character is a comment line. Other lines are composed of tokens. Each token is a character string, and tokens are seperated by one or more of the characters ``space'', ``tabular'' or ``new line''.

Each token is a keyword or data associated to a keyword.

The available keywords are:

• points

  This keyword must be followed by an integer value specifying the number of nodes of a 1D problem and by one decimal value for each node specifying its coordinate.

• value

  This keyword must be followed by one string specifying the name of a scalar variable. This string must be followed by a decimal value for each defined points.

An example (presented in three columns):

# every line beginning by 
# `#' is a comment line
# points 
#number_of_points    # value scalar_value_name
                     # value for each node.
