 In case of iterative solver failure, it is recommended to specially report those variables for which the solver needs an initial guess, but which only have the default value of the \lstinline!start!-attribute as defined in \cref{predefined-types-and-classes}, since the lack of appropriate initial guesses is a likely cause of the solver failure.

-If a parameter has a modifier for the \lstinline!start!-attribute, does not have \lstinline!fixed = false!, and neither has a binding equation nor is part of a record having a binding equation, the modifier for the \lstinline!start!-attribute can be used to add a parameter binding equation assigning the parameter to that \lstinline!start! value.

 In this case a diagnostic message is recommended in a simulation model.
