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:
- recordname
str
Record name. Currently only supports the
"NSL"
record, displacement vectors.- sets
str
orint
Number of sets. Can be
"ALL"
or the number of sets to load.- asarraybool,
optional
Return a
numpy.ndarray
rather than aAnsMath
. DefaultFalse
.
- recordname
- Returns:
numpy.ndarray
oransys.math.core.math.AnsMath
A
numpy.ndarray
orAnsMath
of the displacement vectors, depending on the value ofasarray
.
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, ..., -5.61188243e-03, -7.17686067e-11, 3.71893252e-03], [-1.60960014e-02, 2.00410618e-02, 8.05822565e-03, ..., -1.26917511e-02, -5.14133724e-11, -1.38783485e-03], [ 2.54040694e-02, 3.91901513e-03, -2.67965796e-03, ..., -1.46365178e-02, 8.31735188e-11, -2.33109771e-03], ..., [-2.80679551e-03, -1.45686692e-02, 8.05466291e-03, ..., 5.88196684e-03, 1.72211103e-02, 6.10079082e-03], [-7.06675717e-03, 1.30455037e-02, -6.31685295e-03, ..., 1.08619340e-02, -1.72211102e-02, 2.52199472e-03], [ 2.29726170e-02, 3.54392176e-03, -1.87020162e-03, ..., 1.20642736e-02, 2.58299321e-11, 9.14504940e-04]])
