Use Result Helpers to compare mode shapes for solids and then shells

The Result class which instances are created by the Model gives access to helpers to request results on specific mesh and time scopings. With those helpers, working on a custom spatial and temporal subset of the model is straightforward.

from ansys.dpf import core as dpf
from ansys.dpf.core import examples

First, create a model object to establish a connection with an example result file

model = dpf.Model(examples.download_all_kinds_of_complexity_modal())
print(model)

Visualize specific mode shapes

Choose the modes to visualize

modes = [1, 5, 10, 15]

Choose to split the displacement on solid/shell/beam to only focus on shell elements

disp = model.results.displacement
for mode in modes:
    fc = disp.on_time_scoping(mode).split_by_shape.eval()
    model.metadata.meshed_region.plot(fc.shell_field())
