More ThermoPower models failing with the same message:
https://test.openmodelica.org/libraries/ThermoPower/BuildModelRecursive.html

ThermoPower.Examples.HRB.Simulators.ClosedLoopDigitalSimulator
ThermoPower.Examples.HRB.Simulators.ClosedLoopDigitalSimulatorSimplified
ThermoPower.Examples.HRB.Simulators.ClosedLoopSimulator
ThermoPower.Examples.HRB.Simulators.OpenLoopSimulator
ThermoPower.Examples.HRB.Simulators.OpenLoopSimulatorHtc
ThermoPower.Examples.HRB.Simulators.OpenLoopSimulatorSS
ThermoPower.Examples.HRB.Simulators.OpenLoopSimulatorSimplified

Could be more models there with the same failure.

This may have to do with homotopy and matching/index reduction somehow.
Should we match the variables in the actual or the simplified expression, or both?

Note that when I added rules for diff(homotopy(e1, e2)) -> homotopy(diff(e1), diff(e2))
for #2537 strangely some MSL example became structurally singular: Modelica.Fluid.Examples.HeatingSystem.

comment:3 by Adrian Pop, 11 years ago

One could test with +replaceHomotopy=actual (#2542) to see if the issues come from the homotopy operator handling.

comment:6 by Adrian Pop, 11 years ago

I've tried also with +replaceHomotopy=actual and +replaceHomotopy=simplified
and the model: ThermoPower.Examples.HRB.Models.HRBPlant
is still structurally singular.

Any back-end people have any idea how can we debug this issue?
It might be a problem in the front-end with missing some modifiers
but some pointers on where to look might be good.

Unfortunately I have no other idea than comparing the flattened
equations we get with OpenModelica with what we get with other
tools and that's never an easy job.

Milestone:	1.9.1 → 1.9.2

This ticket was not closed for 1.9.1, which has now been released. It was batch modified for milestone 1.9.2 (but maybe an empty milestone was more appropriate; feel free to change it).

Replying to adrpo:

ThermoPower.Examples.HRB.Models.HRBPlant in ThermoPower (see attached)
or SVN at: http://svn.code.sf.net/p/thermopower/svn/trunk/ThermoPower.

This model has two signal inputs, the gas flow and the valve opening, and is only meant to be connected to appropriate sources for them. If you simulate it alone, they are set to zero, and this brings a lot of singularities.
