D3plot Example

>>> from lasso.dyna import D3plot, ArrayType, FilterType

>>> # read a file (zero-copy reading of everything)
>>> d3plot = D3plot("path/to/d3plot")

>>> # read file buffered (less memory usage)
>>> d3plot = D3plot("path/to/d3plot",
>>>                state_array_filter=["node_displacement"],
>>>                n_files_to_load_at_once=1)

>>> # and of course femzipped files
>>> d3plot = D3plot("path/to/d3plot.fz", use_femzip=True)

>>> # get arrays (see docs of ArrayType for shape info)
>>> disp = d3plot.arrays["node_displacement"]
>>> disp.shape
(34, 51723, 3)
>>> # this is safer and has auto-completion
>>> disp = d3plot.arrays[ArrayType.node_displacement]

>>> # filter elements for certain parts
>>> pstrain = d3plot.arrays[ArrayType.element_shell_effective_plastic_strain]
>>> pstrain.shape
(34, 56372, 3)
>>> mask = d3plot.get_part_filter(FilterType.SHELL, [44, 45])
>>> # filter elements with mask
>>> pstrain[:, mask].shape
(34, 17392, 3)

>>> # create a standalone html plot
>>> d3plot.plot()
