Description of the bug

Hi, everyone,

Whe I've reproduced the 06-animate_results.py example for my Ls-Dyna result (.d3plot) to animate the stress field I got the following error on my end:

Traceback (most recent call last):
  File "d:\Programacao\LS-Dyna\image_gerenator.py", line 55, in <module>
    stress_fields.animate()
  File "D:\Programacao\LS-Dyna\env\Lib\site-packages\ansys\dpf\core\fields_container.py", line 610, in animate
    return anim.animate(
           ^^^^^^^^^^^^^
  File "D:\Programacao\LS-Dyna\env\Lib\site-packages\ansys\dpf\core\animator.py", line 284, in animate
    return self._internal_animator.animate_workflow(
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

  File "D:\Programacao\LS-Dyna\env\Lib\site-packages\ansys\dpf\core\plotter.py", line 265, in add_field
    overall_data[ind] = field.data[mask]
                        ~~~~~~~~~~^^^^^^
IndexError: boolean index did not match indexed array along dimension 0; dimension is 46284 but corresponding boolean dimension is 15428

For the displacement field the animation was generated well.

Can anyone, please, help me solve this problem?

Steps To Reproduce

• Download my LS-Dyna results (d3plot):
  test.zip
• Run the following code:

from ansys.dpf import core as dpf


ds = dpf.DataSources()
ds.set_result_file_path("test\d3plot", "d3plot")
model = dpf.Model(ds)

mesh_scoping = dpf.mesh_scoping_factory.nodal_scoping(model.metadata.meshed_region.nodes.scoping)
time_scoping = dpf.time_freq_scoping_factory.scoping_on_all_time_freqs(model)
stress_op = model.results.stress
stress_op = stress_op.on_time_scoping(time_scoping)
stress_op = stress_op.on_mesh_scoping(mesh_scoping)

stress_fields = stress_op.eval()
stress_fields.animate()

我也出现了这个问题，输入的变量维度不匹配，针对lsdyna solid单元的应力动画提取没有官方案例，官方给的是shell的案例

This issue may be a duplicate of #1435.
I do not however have access to the test file shared anymore. It is empty when I download it.
Please reopen this issue if the fix for the other issue mentioned does not solve your problem.
