I have the following problem: "_Trouble solving algebraic loop containing 'ABT_ON2' at time 0.511. Stopping simulation. There may be a singularity in the solution. If the model is correct, try reducing the step size (either by reducing the fixed step size or by tightening the error tolerances)_" && in the command prompt appears "_Warning: Discontinuities detected within algebraic loop(s), may have trouble solving_"
The strange thing for me is that it starts to run until one signal is switched on. This model consists on a cosimulation with MSC.ADAMS. I have tried to reduce the communication interval but the same problem appears in the same algebraic loop. With the debugger I have seen the three algebraic loops, but no clue is found yet.
Please tell me usual or typical reasons for this problem or a method to look for the cause and fix it.
Thank yo in advance
