General
The given input parser reads and analyzes an input file according to
predefined syntactical rules. It is written in Fortran 2003 (standard, I hope)
and tested on SUN and DEC workstations, as well as on PCs running Windows. It has a unique psychological effect
on any user: "No matter if it works or not - you will wonder why!"
The main idea is to realize a tool, which enables the user to write
position independent (as far as possible) input files. The input files can
be changed without recompiling the parser. The parser checks the input file
for syntactical correctness, for the presence of required input and for
correctness of the data types of the given variable values.
- Fortran input parser
input_parser.zip
This is a simple test example (Fortran 2003 code) of Günther
Zandler's famous input parser that is used inside nextnano³.
Maybe you got already familiar with it and want to use it in your own
code.
- Input parser:
General
This manual provides general infomation on keywords
and specifiers that are used for
treating the input files. This is important if you want to add additional keywords
and additional specifiers
in the files
keywords.in and
database.in.
- Input parser: Keywords
General introduction to some of the keywords and
specifiers including some examples.
- General program layout
This is a description how the main driving routine
(MODULE
input_driver_module)
works (used
for reading input parameters, database information as well as
processing and checking the corresponding quantities).
- Input
scaling quantities and physical constants
All input quantities are assumed to be given in
scaled form.
This is important for the material parameters in the
database.in file.
-
$input-scaling-factors
- $physical-constants
- Keywords
Here you can find detailed information for each individual
keyword and its specifiers, e.g. start with
-
Simulation coordinate system
What is the dimension of your simulation region/sample?
Description of the keyword
$simulation-dimension
together with its specifiers dimension and
orientation.
- Domain
coordinates
Information about the overall simulation domain,
that is the real space region in which the device
is defined, - orientation of crystal and substrate.
Program documentation
Recent changes to the input parser
- Input parser can be activated several times during a program run.
- Added macro feature.
- Added function parser feature.
- Allow for single precision input (and convert it automatically into
double precision).
- TABs are now allowed.
