Post-processing#

Factory functions#

`create_envelope`(**kwargs)	Create an envelope object for post-processing result envelopes.
`plot_force`(ospgrillage_obj[, result_obj, ...])	Plot a force diagram for a grillage model result for a specified component and load case.
`plot_defo`(ospgrillage_obj[, result_obj, ...])	Plot a displacement diagram for a grillage model result for a specified component and load case.

class Envelope(ds, load_effect=None, **kwargs)#

Bases: object

Class for defining envelope of OspGrillage’s xarray of result.

A Envelope.get() method is provided that returns an enveloped xarray based on the specified input parameters of this class.

Parameters:

ds (Xarray) – Data set from get_results() . note Combination
load_effect (str) – Specific load effect to envelope.
array (str, optional) – Data array to envelope — either "displacements" or "forces".
value_mode (bool, optional) – If True, return raw envelope values. Defaults to True.
query_mode (bool, optional) – If True, return the load case coordinate at the envelope extrema. Defaults to False.
extrema (str, optional) – Envelope direction — either "min" or "max".
elements (list, optional) – Specific element tags to include in the envelope.
nodes (list, optional) – Specific node tags to include in the envelope.

class PostProcessor(grillage, result)#

Bases: object

Class to post-process the results from an of ospgrillage analysis result.

As of version 0.2.0, ospgrillage compiles results using Xarray module.
