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
