Issue with Importing Multiple `output_dict.yml` Files

[lukas-koschmieder]

Description

We are working with a workflow consisting of n simulation nodes followed by a final visualization node that aggregates and plots the data.

Each simulation node generates a file named output_dict.yml to pass specific data to the report generator. However, we have noticed that the visualization node cannot import these files using the wildcard method in the WaNoFile element.

Expected Behavior

SimStack should import all n output_dict.yml files into the exec_directory of the visualization node as follows:

• 0_output_dict.yml
• 1_output_dict.yml
  ...
• (n-1)_output_dict.yml

Observed Behavior

Instead, SimStack imports only one of the files as:

• output_dict.yml

Workaround

As a workaround, we symlinked output_dict.yml to output.yml. Using this approach, SimStack correctly imports the files as:

• 0_output.yml
• 1_output.yml
  ...
• (n-1)_output.yml

We believe this behavior is a bug and would appreciate if this could be addressed.
