Input file syntax

Relevant module: edelweissfe.utils.inputfileparser.py

EdelweissFE uses an input file syntax similar to Abaqus, using human readable input files. The general syntax makes use of *keywords, possibly with option=values in the same line and supplemented by data lines. In general, options and data entries are comma separated. Indentations and blank lines have no effect.

*keyword, option1=value, option2=another_value
data, data, data, data
data, data, data, data
data, data, data, data

**this is a comment
**again a comment

*another_keyword, option1=value, option2=another_value
data, data, data, data

The available input syntax is defined in fe/utils/inputfileparser.py, and available keywords can be printed using

python edelweiss.py --keywords

Inputfileparser for inputfiles employing an Abaqus-like syntax.

edelweissfe.utils.inputfileparser.parseInputFile(fileName, currentKeyword=None, existingFileDict=None)

Parse an Abaqus-like input file to generate a dictionary with its content.

Parameters

• fileName (str) – The name of the file to parse.

• currentKeyword (str) – If nested parsing is performed by using *include, this option tells which keyword is currently active.

• existingFileDict (CaseInsensitiveDict) – An existing dictionary to append. If Nonde, a new dictionary is created.

Returns

The parsed input file.

Return type

CaseInsensitiveDict

edelweissfe.utils.inputfileparser.printKeywords()

Print the input file language set.

edelweissfe.utils.inputfileparser.printKeywordsRST()

Print the input file language set in an RST conform format.
