Example to access LS-Dyna results not working

[BastiLoe]

Hello all,

I am new to this library and I am trying to access LS-Dxna data. I started up with the example: https://dpf.docs.pyansys.com/version/stable/examples/14-lsdyna/00-lsdyna_operators.html#sphx-glr-examples-14-lsdyna-00-lsdyna-operators-py

When running the line print(model) I am getting: KeyError: "The operator stream_provider doesn't exist in the registry. Check its spelling in the documentation or verify its availability in your loaded plugins. The current available operator names can be accessed using 'available_operator_names' method."

dpf.available_operator_names()
['Buffer', 'chunk_fc']

Seems the stream_provider-Operator is missing? What is an operator, how to get it? This happens for all d3plot- or binout-data I am trying to access, not only for the example. Can someone help me to solve this issue? Thanks.

Hi @BastiLoe,
it looks like this is an installation issue. In theory there should be hundreds of operators shown as available, and among them some dedicated to lsdyna.

Could you maybe describe your setup? Such as OS, Python version, a pip freeze, and the version of the Ansys installation.
