I was trying to simulate a simple fluids model that i built up with OMEdit
The Simulation-Output-window says that the Simulation process failed and the grid shows no results. Why does that happen?
Here's my sourcecode:


model Test_Abfueller
  Modelica.Fluid.Vessels.OpenTank tank(redeclare package Medium = Modelica.Media.CompressibleLiquids.LinearColdWater, crossArea = 1, height = 1, level_start = 23, nPorts = 1)  annotation(
    Placement(visible = true, transformation(origin = {62, 4}, extent = {{-20, -20}, {20, 20}}, rotation = 0)));
  Modelica.Fluid.Pipes.StaticPipe pipe(redeclare package Medium = Modelica.Media.CompressibleLiquids.LinearColdWater, diameter = 0.05, length = 1)  annotation(
    Placement(visible = true, transformation(origin = {-30, -28}, extent = {{-10, -10}, {10, 10}}, rotation = 0)));
  inner Modelica.Fluid.System system annotation(
    Placement(visible = true, transformation(origin = {-70, 70}, extent = {{-10, -10}, {10, 10}}, rotation = 0)));
  Modelica.Fluid.Sources.Boundary_pT boundary(redeclare package Medium = Modelica.Media.CompressibleLiquids.LinearColdWater, T = 278, nPorts = 1, p = 600000)  annotation(
    Placement(visible = true, transformation(origin = {-92, -28}, extent = {{-10, -10}, {10, 10}}, rotation = 0)));
equation
  connect(pipe.port_b, tank.ports[1]) annotation(
    Line(points = {{-20, -28}, {28, -28}, {28, -46}, {62, -46}, {62, -16}}, color = {0, 127, 255}));
  connect(boundary.ports[1], pipe.port_a) annotation(
    Line(points = {{-82, -28}, {-40, -28}, {-40, -28}, {-40, -28}}, color = {0, 127, 255}, thickness = 0.5));
  annotation(
    uses(Modelica(version = "3.2.2")));
end Test_Abfueller;

I hope someone can help me with this. I'd appreciate any help.
