Description (last modified by adrpo)
It seems the initialization goes into an infinite loop when simulating this model:
Modelica.Mechanics.MultiBody.Examples.Systems.RobotR3.fullRobot.

The initialization is even with simulation-flag -iom kinsol wrong.
But using the new symbolic initialization, the initialization works fine. (omc fullRobot.mos +d=solveinitialsystem).
Note: See
TracTickets for help on using
tickets.
By changing the initialization method to kinsol (simflags="-iom kinsol") it seems that it initialize
fast and correct. But then it stucks with a kind of event chattering. I think that's related to Ticket #1866, which I want so solve this week.
