Description
In r24915 cellier method is activated again for big algebraic loos. In combination with addDerAlias modules it causes issues so that tearing fails for example for the following model:
ThermoPower.Examples.HRB.Simulators.ClosedLoopDigitalSimulator ThermoPower.Examples.HRB.Simulators.ClosedLoopDigitalSimulatorSimplified ThermoPower.Examples.HRB.Simulators.ClosedLoopSimulator Modelica.Fluid.Examples.HeatExchanger.HeatExchangerSimulation

Ongoing re-structuring of OMC-Backend in order to improve symbolic treatment of underlying DAEs.
Should make it possible to replace current workaround with a stable solution.

This has nothing to do with addDerAlias, it also fails without.

The problem was that sometimes discrete iteration variables are necessary to find a tearing set, which was excluded by the tearing method. This is fixed in f1fc675/OMCompiler. Now discrete iteration variables are allowed if there is no other possibility.
