RuntimeError: The network has only one outlet

[johannesring]

After the recent commit aa9d0d, which introduced changes to the setup_model_network function in preprocessing_common.py, I get the following error when trying to generate a mesh for models with only one inlet and one outlet:

Traceback (most recent call last):
  File "/home/johannr/miniconda3/envs/vampy/bin/vampy-mesh", line 8, in <module>

RuntimeError: The network has only one outlet.

To reproduce this, try to run the mesh generation for a model with only one inlet and one outlet, such as a cylinder or stenosis.

Before the mentioned commit, this worked fine. Is this something that should be supported by vampy-mesh?

@johannesring Thanks for reporting this!

Models with one outlet and one inlet must have been overlooked during the commit you referred to. I have made a fix and added a test (one inlet, one outlet model) for this in PR #131.

I hope this resolves the issue.

[johannesring]

Yes, that fixed the problem. Thanks!

[johannesring]

Fixed in PR #131.
