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())
