How can I plotting a half model to a full model ?

[ufsaa2022]

I performed the analysis with a symmetric model.

So I want to plot the result as if it were a full model.

Is there any way?

Thank you,

I think not straight away in PyMAPDL.

However, you can do something (pseudo-code):

# Getting element plot
pl = mapdl.eplot(return_plotter=True)
# Getting elements + results plot
pl = mapdl.post_processing.displacements("x", return_plotter=True)

# Post processing with pyvista:
mesh = pl.grid

# use reflect for half-symmetry. https://docs.pyvista.org/examples/01-filter/reflect.html

Also, you can have a look at:

https://mapdl.docs.pyansys.com/examples/gallery_examples/00-mapdl-examples/cyclic_analysis.html?highlight=cyclic

However, it uses the old pymapdl-reader (in deprecating process).

Hi @dhkimmm & @germa89
Please see the MAPDL Commands Guide (in the Ansys Help) entry on /EXPAND or EXPAND. /EXPAND is a generic feature to show symmetric FEMs, with or without the results, in an expanded (full 3D) view. If I remember correctly it repeats what is presented to be plotted (i.e. does not actually create additional nodes/elements). /EXPAND is specific to modal cyclic symmetric models and does create nodes/elements. You would then need to post-process with native MAPDL commands in PyMAPDL and not the post_processing method.
