nodal_thermal_principal_strain

PostProcessing.nodal_thermal_principal_strain(component)

Nodal thermal principal thermal strain.

Equivalent MAPDL commands:

  • *VGET,PARM,NODE,,EPTH,1

Parameters
componentstr, optional

Component to retrieve. Must be '1', '2', or '3'

Returns
numpy.ndarray

Numpy array containing the nodal thermal principal thermal strain for the specified component.

Notes

This command always returns all nodal rotations regardless of if the nodes are selected or not. Use the selected_nodes mask to get the currently selected nodes.

Examples

Principal nodal strain in the S1 direction for the first result.

>>> mapdl.post1()
>>> mapdl.set(1, 1)
>>> mapdl.post_processing.nodal_thermal_principal_strain('1')
    array([0.60024621, 0.61625265, 0.65081825, ...,
           0.        , 0.        , 0.        ])

Corresponding nodes.

>>> mapdl.mesh.nnum_all
array([   1,    2,    3, ..., 7215, 7216, 7217], dtype=int32)
Return type

ndarray
