Hi Julia,
There are plenty of components that read and/or load things from a BF case. Depends on what you want to achieve really.
- The look up case folder which finds the relevant text files of your case for easy reference.
- The sample case which will export probe locations and values.
- The load mesh that will load the mesh of the case (care should be taken when loading large cases).
In order to access all that though you would first have to actually re-load the case itself (i.e. the actual BF case created during the original run. To do that you can connect the case output of your Butterfly_Create_case_from_Tunnel component to the Butterfly_solution component directly. Then, with setting true for write and false for run you can simply re-run your Butterfly_Create_case_from_Tunnel component and your results should reload. You can then use the outputs of the Butterfly_solution component for other post-processing components.
As a suggestion, I would consider using paraview (paraview.org/download/) for a more efficient post-processing.
Hope this helps!
Kind regards,
Theodore.
