Bound Parameter Expression unfixed

Reported by: Jens Frenkel Owned by: Jens Frenkel
Priority: high Milestone: 1.9.0
Component: Backend Version: trunk
Keywords: Cc: Willi Braun, Lennart Ochel

Description

The following model is not possible to simulate with the current implementation 

model BoundParameterExpUnfixed
  parameter Real a(fixed=false,start=1);
  parameter Real b = 2*a;
  Real x;
initial equation
  sin(a) = 1;
  der(x) = 2;
equation
  der(x) + x = b;
end BoundParameterExpUnfixed;

The problem is we do not seperate
Parameter with fixed bindings
Parameter with unfixed bindings

The model is also in testsuite/simulation/modelica/initialization
