Idealized Contact 0.2.0 library

[francesco.cavenago@…]

I tried to simulate IdealizedContact.Examples.Example1 in OMEdit and the following error message was thrown:

[1] 09:48:28 Translation Error
[Modelica.Mechanics.MultiBody.Parts: 1849:5-1860:58]: Variable contact.contactDefinition.geometry.Animation not found in scope Modelica.Mechanics.MultiBody.Parts.PointMass$contact$contactDefinition$geometry$contact_point_ball1.

similar error is thrown also simulating other examples.

Also have a look here:

Can you please check if this particular issue still remains in the latest release of OpenModelica? For me the model flattens without errors, but the generated system is over-determined (i.e. has more equations than variables) and can't be simulated.

I'd close this as a duplicate of #4471

Replying to sjoelund.se:

I'd close this as a duplicate of #4471

I tried with the latest release (1.12.0), I have some warnings and the over-determined system:

[1] 11:15:37 Translation Warning
[IdealizedContact: 715:37-715:47]: Non-array modification 'true' for array component, possibly due to missing 'each'.

[2] 11:15:37 Translation Warning

[5] 11:15:37 Symbolic Error
Too many equations, over-determined system. The model has 4398 equation(s) and 4392 variable(s).

I can move my question to #4471 , so you can close this.
