3729	Models of trunk/Modelica that do not simulate in OpenModelica (and are not present in MSL 3.2.1 failed simulations)	martin.otter@…	somebody	"When comparing the simulation results of MSL 3.2.1 with trunk:

https://test.openmodelica.org/hudson/job/MSL_3.2.1_Simulation/894/#showFailuresLink, Build #894 (Feb 28, 2016 8:17:37 AM) 

with

https://test.openmodelica.org/hudson/job/MSL_trunk_Simulation/860/#showFailuresLink, Build #860 (Feb 28, 2016 8:22:08 AM)

then the following models are either not present in MSL 3.2.1 or simulate in MSL 3.2.1 but not in trunk:

{{{
Modelica.Electrical.Analog.Examples.OpAmps.SignalGenerator
- Fails with DASSL (nonlinear equation solver fails)
- Simulates with Radau5
    
Modelica.Electrical.Analog.Examples.OpAmps.Multivibrator
- Fails with DASSL and Radau5 (nonlinear equation solver fails)
- Simulates with trapezoid
     Modelica.Electrical.Machines.Examples.SynchronousInductionMachines.SMPM_Braking
- Fails with DASSL, Radau5, Trapezoid (nonlinear equation solver fails)
- Simulates in Dymola, but with a
  WARNING: You have many state events. It might be due to chattering.
  Changing Vknee in the diodes from 0 to 0.8 (= more realistic diode model)
  removes the chattering warning in Dymola (and about 5 times less state events).
       Modelica.Magnetic.FundamentalWave.Examples.BasicMachines.AIMC_DOL_MultiPhase
- Fails with DASSL, Radau5, Trapezoid (nonlinear equation solver fails)
      Modelica.Magnetic.FundamentalWave.Examples.BasicMachines.SMPM_Inverter_MultiPhase
- Fails with DASSL, Radau5, Trapezoid (nonlinear equation solver fails)
        Modelica.Magnetic.FundamentalWave.Examples.BasicMachines.SMR_Inverter_MultiPhase
- Fails with DASSL, Radau5, Trapezoid (linear equation solver fails)
    
Modelica.Fluid.Examples.IncompressibleFluidNetwork
- Compilation took too long, so I stopped.
- Unclear, because the last change of this model was in 2013, and then this
      model should fail with MSL 3.2.1 and with trunk, but it fails only in trunk
