Hello Nektar users,

I would like to simulate a merging junction using the PulseWaveSolver but struggle to do so.

As a guide I used the Merging.xml file in PulseWaveSolver > Examples > Merging.xml, however the example is not a merging junction.

I confirmed this through the following print command in PulseWaveSystem.cpp which returns 0 (and 1 for bifurcations)

cout << "Number of merging junctions: " << m_mergingJcts.size() << std::endl;

So, I decided to start from scratch. I can construct any arbitrary network geometry with segments and bifurcations but not if I add a merging junction.

The reason my merging junction cannot converge is because P_Au becomes -nan

I have tried many different configurations but did not succeed hence I finally decided to reach out.

Do you have any suggestion for me or in the best case a minimal working example of a merging junction model.xml file?

Best wishes,

Kai
