class viktor.external.scia.scia.SciaAnalysis(input_file, xml_def_file, scia_model, calculation_setting=CalcSetting.LIN, xml_doc_name='output', *, result_type=ResultType.MODEL, output_document='')

Bases: ExternalProgram

SciaAnalysis can be used to perform an analysis using SCIA on a third-party worker. To start an analysis call the method execute(), with an appropriate timeout (in seconds). To retrieve the output file call the method get_xml_output_file() after execute().

Usage:

input_file = BytesIO("scia input file content".encode())
xml_def_file = BytesIO("scia xml def file content".encode())
scia_model = BytesIO("scia model content".encode())
scia_analysis = SciaAnalysis(input_file=input_file, xml_def_file=xml_def_file, scia_model=scia_model)
scia_analysis.execute(timeout=600)
xml_output_file = scia_analysis.get_xml_output_file()

Besides the output XML file, you can also retrieve the updated SCIA model. This is achieved using the result_type:

scia_analysis = SciaAnalysis(input_file=input_file, xml_def_file=xml_def_file, scia_model=scia_model,
                             result_type=ResultType.MODEL)
scia_analysis.execute(timeout=600)
updated_esa_file = scia_analysis.get_updated_esa_model()

or the Engineering Report:

scia_analysis = SciaAnalysis(input_file=input_file, xml_def_file=xml_def_file, scia_model=scia_model,
                             result_type=ResultType.ENGINEERING_REPORT, output_document='report1')
scia_analysis.execute(timeout=600)
engineering_report = scia_analysis.get_engineering_report()

generate_xml_input(as_file=False)

Returns the input file XML representation of the SCIA model and corresponding .def file.

Note

OutputFileParser​

class viktor.external.scia.scia.OutputFileParser

Helper class to extract results from a SCIA output file (.xml).

Example using BytesIO:

xml_output_file = scia_analysis.get_xml_output_file()
result_table = OutputFileParser.get_result(xml_output_file, 'Reactions')
another_result_table = OutputFileParser.get_result(xml_output_file, '2D internal forces')

Example using File:

xml_output_file = scia_analysis.get_xml_output_file(as_file=True)
with xml_output_file.open_binary() as f:
    result_table = OutputFileParser.get_result(f, 'Reactions')
    another_result_table = OutputFileParser.get_result(f, '2D internal forces')
classmethod get_result(file, table_name, *, parent=None)

Retrieve the results of an output XML by ‘table_name’. This corresponds to the ‘name’ attribute that is found in the XML table, e.g. “Result classes - UGT” in the example below:

<container id="..." t="...">
    <table id="..." t="..." name="Result classes - UGT">

In case indenting has been used in the SCIA I/O doc, multiple tables with the name ‘table_name’ will be found. A parent name can be specified as input to account for this indenting (up to 1 indent level). If indenting is used but no parent name is specified, this method will return the first ‘table_name’ table it can find.

Parameters:

  • file (BinaryIO) – SCIA output file (.xml).

  • table_name (str) – Name of the result table to be extracted from the output XML.

  • parent (str) – Name of the parent, e.g. a result class.

Return type:

Dict[str, dict]

:raises viktor.errors.SciaParsingError:

  • if table ‘table_name’ could not be found in the provided output file

  • if no results were found in the XML table ‘table_name’
