Changed system.m_flow_nominal from 1 to 0.1, and eps_m_flow from 1e-4 to 1e-2. The first change was done to get reasonable values for dp_nominal (e.g., 9.7 Pa instead of 682 Pa, which is closer to the actual pressure drop which is around 5 Pa). The change in eps_m_flow was needed to avoid the solver (dassl from Dymola 2013 FD01) to stall after a step change.
