Description of the bug

If you want to plot the displacement from rst file without input a mesh you cannot plot the resulting field with this error

This is due to the fact that for this kind of result, the mesh support is empty by default.

Steps To Reproduce

path = r"path_to\ASimpleBar.rst"

dataSource = dpf.DataSources()
dataSource.set_result_file_path(path, "rst")

stream_prov = dpf.operators.metadata.streams_provider(data_sources=dataSource)
stream_prov.connect(0,1)
stream_c = stream_prov.outputs.streams_container

result_op = dpf.operators.result.displacement()
result_op.inputs.streams_container(stream_c)
result_fc = result_op.outputs.fields_container()

field = result_fc[0]
field .plot()

Hey @MichaelNale,

Could you explain what that line is meant to do:
stream_prov.connect(0,1)

I reproduced with or without that line, but I want to make sure your point in the issue was not specifically related to that line being there.

This was a leftover for sure
