OpenModelica Warning for fluids model

edit

Hi All,

I have a pretty simple model of a fluid being driven to flow from high pressure to low pressure. The simulation works but I keep getting this lengthy warning.

WARNING

No corresponding 'inner' declaration found for component .Modelica.Fluid.System pipe.system declared as 'outer '. The existing 'inner' components are: There are no 'inner' components defined in the model in any of the parent scopes of 'outer' component's scope: Modelica.Fluid.Pipes.StaticPipe$pipe. Check if you have not misspelled the 'outer' component name. Please declare an 'inner' component with the same name in the top scope. Continuing flattening by only considering the 'outer' component declaration.
