So, adding the following lines before the addToNode() line at least allows this to run without terminating.
performance_multispeed = OpenStudio::Model::UnitarySystemPerformanceMultispeed.new(model)
performance_multispeed.setSingleModeOperation(false)
performance_multispeed.addSupplyAirflowRatioField(1.0,1.0)
performance_multispeed.addSupplyAirflowRatioField(1.0,1.0)
performance_multispeed.addSupplyAirflowRatioField(1.0,1.0)
unitary_system.setDesignSpecificationMultispeedObject(performance_multispeed)
Unfortunately, there is no cooling, so there is another hurdle to cross.
