Buildings.Examples.DualFanDualDuct.ClosedLoop
Simulation that hangs. The dslog.txt file is empty and the simulation window does not show any diagnostics.
For comparison, with Radau, 1E-6, the simulation takes 4 seconds; if changed to cvode, 1E-6, the simulation fails at time = 19873.6; if changed to dassl, 1E-6, the simulation hangs around time = 20000.
