classmethod biaxial(**kwargs)#

A single-step biaxial load case.

See biaxial() for argument documentation.

Return type:: Self

create_damask_loading_plan()#

Turn this load case into a DAMASK loading plan.

Return type:: list[dict[str, Any]]

classmethod dump_element_group_to_HDF5_group(objs, group)#

Write a list (from an element group) of parameter values to an HDF5 group.

Parameters:

objs (list[Self]) –

Return type:: Self

classmethod from_npz_file(**kwargs)#

Importing loadcase from npz file

classmethod multistep(steps)#

A load case with multiple steps.

Parameters:: steps (list[dict[str, Any] | matflow.param_classes.load.LoadStep]) – A list of LoadStep objects or dict`s representing `LoadStep objects, in which case if a dict has a key type, the corresponding LoadStep classmethod will be invoked with the remainder of the dict items.
