Description
when checking Modelica.Electrical.Analog.Examples.CauerLowPassSC the following error message appears:
Class Modelica.Electrical.Analog.Examples.CauerLowPassSC has 559 equation(s) and 559 variable(s).
353 of these are trivial equation(s).
"
"Warning: Parameter V has no value, and is fixed during initialization (fixed=true)
Error: No constant value for variable V in scope Modelica.Electrical.Analog.Sources.StepVoltage.
"
"
However, it works fine to simulate in MathModelica. The error message is wrong, since a value DO exist for V.

It's not an error message; it's a warning. It's a parameter without binding. It has a start value, which should be overridden by a binding (this is not performed on purpose in the MSL examples).
