How can I gather element table data of a sub-set of elements?

Mike Rife

PyMAPDL has additional methods of retrieving just the data from Mechanical APDL listings. As an example we want to gather a list of lists of some result, like Y deformation, for a sub-set of elements from a full harmonic analysis. This example is a simple 24x4 square shell mesh with one end fixed and the other end an applied force in Y.

mapdl.post1()
mapdl.esel('s','cent','x',15.5)
mapdl.nsle()

results = []

for sub in range(1,21):
    mapdl.set(1, sub, 'velo', 'ampl')
    etable = mapdl.etable('uyetab', 'u', 'y')
    etable_list = mapdl.pretab('uyetab').to_list()
    results.append(etable_list)
mapdl.allsel()

The list 'results' is then (16, 40, 64, 88 are the element IDs of the selected elements):

I should have added that the PyMAPDL post processing method post_processing.element_values() will return an Numpy array of just the data.
