``Extractor.py'' is a package for automatic extraction (and checking) of user-defined values from OOFEM output file. The values to be extracted are defined in extractor input file. The tool can operate in two modes:

• Extraction mode, where for each solution step, the tool finds specific values and prints them on output, one row per each solution step. In particular columns are the extracted values, preserving their order as specified in input file.
• Checking mode, where the specific values are located in oofem output file and are compared to the values given. It the difference is larger than given tolerance, an error is issued.

The program parameters are following

extractor [-c] -f inputFileNamePath

The inputFileNamePath is the path to input file, containing description of user-defined values to be extracted or checked. The -f option is compulsory. If not supplied, the program prints usage information and exits. The -c flag turn on the checking mode. If not set, the extraction mode is used by default.

The format of extractor input file consists of two compulsory sections, the source file section, followed by the value records section, that determines the values to be extracted or checked.
