This is the result of running:

 loadModel(Modelica);
 checkAllModelsRecursive(Modelica);

Filtered so just the failing models are included.

[Martin Sjölund]

Only the following models now give errors. Some because they are partial and should not work.

Error: Error occured while flattening model Modelica.Blocks.Continuous.TransferFunction
Error: Error occured while flattening model Modelica.Blocks.Continuous.StateSpace
Error: Error occured while flattening model Modelica.Blocks.Sources.KinematicPTP
Error: Error occured while flattening model Modelica.Blocks.Sources.KinematicPTP2
Error: Error occured while flattening model Modelica.Electrical.Analog.Interfaces.VoltageSource
Error: Error occured while flattening model Modelica.Electrical.Analog.Interfaces.CurrentSource
Error: Error occured while flattening model Modelica.Mechanics.MultiBody.Interfaces.PartialLineForce
Error: Error occured while flattening model Modelica.Mechanics.MultiBody.Types.RotationSequence

I used echo "loadModel(Modelica);" > x.mos ; grep -o Modelica.*\ c | sed "s/^/x:=instantiateModel(/" | sed "s/ \$/) == \"\"; echo(false);y:=getErrorString();echo(true);if x then print(y); end if;/" >> x.mos; omc x.mos > log; grep flattening log to generate the report :)

[Martin Sjölund]

checkModel works on all the models, so I am closing the bug.
