FMU containing Revolute joint crashes
FMU containing Revolute joint crashes
Jan-12-17 07:57:14
Hello,
I generated several FMUs ver. 2.0 containing the Modelica.Mechanics.MultiBody.Joints.Revolute model. All these FMUs cause the crash of the FMUChecker tool. The same crash I obtained after import of these FMUs to Matlab-Simulink and also to our own software. It seems that the same problem is in both variants - Model Exchange and CoSimulation. Please, see the attached very simple example.
Best regards

Thank you

The code for the post above is this one:
Code:
model RevoluteCrash
import SI = Modelica.SIunits;
parameter SI.RotationalDampingConstant d(final min=0, start=1.5)
"Damping constant";
inner Modelica.Mechanics.MultiBody.World world(n = {0, 0, -1}) annotation(Placement(visible = true, transformation(origin = {-70, 70}, extent = {{-10, -10}, {10, 10}}, rotation = 0)));
Modelica.Mechanics.MultiBody.Joints.Revolute revolute1(n = {0, 1, 0}, phi(displayUnit = "rad"), useAxisFlange = true) annotation(Placement(visible = true, transformation(origin = {-34, 70}, extent = {{-10, -10}, {10, 10}}, rotation = 0)));
Modelica.Mechanics.MultiBody.Parts.Body body1(m = 0.5, r_CM = {0, 0, -1}) annotation(Placement(visible = true, transformation(origin = {6, 70}, extent = {{-10, -10}, {10, 10}}, rotation = 0)));
equation
connect(revolute1.frame_b, body1.frame_a) annotation(
Line(points = {{-24, 70}, {-4, 70}}, color = {95, 95, 95}));
connect(world.frame_b, revolute1.frame_a) annotation(
Line(points = {{-60, 70}, {-44, 70}, {-44, 70}, {-44, 70}}, color = {95, 95, 95}));
end RevoluteCrash;
