extract

ansXpl.extract(recordname, sets='ALL', asarray=False)

Import a Matrix/Vector from a MAPDL result file.

At the moment, this only supports reading the displacement vectors from a result file.

Parameters:

recordnamestr

Record name. Currently only supports the "NSL" record, displacement vectors.

setsstr or int

Number of sets. Can be "ALL" or the number of sets to load.

asarraybool, optional

Return a numpy.ndarray rather than a AnsMath. Default False.

Returns:

numpy.ndarray or ansys.math.core.math.AnsMath

A numpy.ndarray or AnsMath of the displacement vectors, depending on the value of asarray.

Notes

This only works on the "NSL" record of MAPDL result files.

Examples

First, open a result file and extract the displacement vectors for all sets.

>>> xpl.open("file.rst")
>>> mat = xpl.extract("NSL")
>>> mat
Dense APDLMath Matrix (243, 10)

Convert to a dense numpy array

>>> arr = mat.asarray()
>>> arr
array([[-9.30806802e-03, -2.39600770e-02, -5.37856729e-03, ...,
