I haven’t run across anything. This post suggests interest in doing that, but I don’t see an followup work at Modelon. Julia is good at wrapping C code. You might have a look at wrapping FMILibrary. You could also try using PyFMI through Julia’s Python interface.
Maybe you could convert your Modelica models to Modia. You might also have a look at OMJulia, a Julia interface to OpenModelica.
