element_values

PostProcessing.element_values(item, comp='', option='AVG')

Compute the element-wise values for a given item and component.

This method uses Mapdl.etable() <ansys.mapdl.core.Mapdl.etable() and returns a numpy.ndarray rather than storing it within MAPDL.

Parameters
itemstr

Label identifying the item. See the table below in the notes section.

compstr, optional

Component of the item if applicable. See the table below in the notes section.

optionstr, optional

Option for storing element table data. One of the following:

  • "MIN" : Store minimum element nodal value of the specified item component.

  • "MAX" : Store maximum element nodal value of the specified item component.

  • "AVG" : Store averaged element centroid value of the specified item component (default).

Returns
numpy.ndarray

Numpy array containing the requested element values for ta given item and component.
