6040	Output variables changing name in FMU	Andreas Heuermann	Andreas Heuermann	"When declaring a variable as an output and generating a FMU the variable name gets changed.

Run
{{{
loadString(""
model simpleOutput
  output Real x (fixed=true, start=1);
  Real y (fixed=true, start=2);
  parameter Real a=2;
equations
  der(x) = a*x;
  der(y) = a*y;
end simpleOutput;
""); getErrorString();

buildModelFMU(simpleOutput); getErrorString();

system(""unzip -p simpleOutput.fmu modelDescription.xml > modelDescription.xml""); getErrorString();
}}}

and than the modelDescription.xml will contain
{{{
