sfepy.postprocess.time_history module¶
-
sfepy.postprocess.time_history.average_vertex_var_in_cells(ths_in)[source]¶ Average histories in the element nodes for each nodal variable originally requested in elements.
-
sfepy.postprocess.time_history.dump_to_vtk(filename, output_filename_trunk=None, step0=0, steps=None, fields=None, linearization=None)[source]¶ Dump a multi-time-step results file into a sequence of VTK files.
-
sfepy.postprocess.time_history.extract_time_history(filename, extract, verbose=True)[source]¶ Extract time history of a variable from a multi-time-step results file.
Parameters: - filename : str
The name of file to extract from.
- extract : str
The description of what to extract in a string of comma-separated description items. A description item consists of: name of the variable to extract, mode (‘e’ for elements, ‘n’ for nodes), ids of the nodes or elements (given by the mode). Example: ‘u n 10 15, p e 0’ means variable ‘u’ in nodes 10, 15 and variable ‘p’ in element 0.
- verbose : bool
Verbosity control.
Returns: - ths : dict
The time histories in a dict with variable names as keys. If a nodal variable is requested in elements, its value is a dict of histories in the element nodes.
- ts : TimeStepper instance
The time stepping information.
-
sfepy.postprocess.time_history.extract_times(filename)[source]¶ Read true time step data from individual time steps.
Returns: - steps : array
The time steps.
- times : array
The times of the time steps.
- nts : array
The normalized times of the time steps, in [0, 1].
- dts : array
The true time deltas.
-
sfepy.postprocess.time_history.guess_time_units(times)[source]¶ Given a vector of times in seconds, return suitable time units and new vector of times suitable for plotting.
Parameters: - times : array
The vector of times in seconds.
Returns: - new_times : array
The vector of times in units.
- units : str
The time units.
