Hi Wendelin,
For me it works perfectly fine.
Are you sure you loaded the Modelica
library via a script command first?
See Electric.mos
Cheers,

Hi,
I am trying to simulate models using electrical parts of the Modelica-lib but
openmodelica fails to flatten the models.
Above a minimal example.
Any suggestions?
Is there a list which parts of the Modelica-lib should actually be supported by
openmodelica?
Cheers,
Wendelin
