class restflow.hf3binding.Hiflow3Session(working_dir)

Bases: restflow.base.AbstractHf3Session

This class handles session of the elasticity executable.

• It holds both configuration files (bcdata and hf3data) in memory.
• It sets the last mesh as the input of the next run
• Provides access to results

bcdataxml()

Returns the bc data as xml string. :rtype: str

get_result(step)

Returns the filename for step

This is a pvtu file.

Return type:path.path

get_result_files()

Returns all result files after SOLUTION_FILENAME

Returns:a list of path.path Return type:list[path.path]

hf3xml()

Returns hf3 data structure as xml string :rtype: str

run()

Runs elasticity.

• First prepares the configuration files for the run (`self._run´). * sets the last mesh result as new input mesh
• Creates output folder

Raises:BaseException if elasticity returned with errorlevel != 0, checkout self.workingdir/outptu_{self._run}.txt for more information. Returns:something undefined

working_dir

the working dir for elasticity (holds all configs and results)

restflow.hf3binding.SOLUTION_FILENAME = '_deformedSolution_np{np}_RefLvl{rlvl}_Tstep.{step}.pvtu'

Filename of result files written by elasticity. Filename is parameterized by:

Np:number of parallel threads Rlvl:refinement level Step:step

restflow.hf3binding.md(*args)

creates an directory silently
