FE Element Cosimulation with Simulink

alexander.bil
Hello everyone,
 
I was trying to do a cosimulation in Simulink. I have created a FE-Element object in ADAMS but I get an error message while simulating in Simulink. It says the generated S-Function has an error. I did the same as with other cosimulations that are working.
 
Is it possible that Cosimulation is not supported for FE-Elements?
 
Yes or No answer is already helpful!
 
Thanks

    Hi Alexander,
    You are correct: the new FE_PART does not work with co-simulation. I recall seeing this documented somewhere, but I note the FE_PART docs in the Solver guide don't list this. I will log a defect report to get our documentation fixed AND to ask that it at least work in discrete co-sim mode.
     
    I assume that you are in discrete co-sim, right? I discussed with my colleague in Product Development and he indicated that we could likely enhance it for the future to work in discrete co-sim, but 'function evaluation' mode would be a lot trickier to implement. I believe that most people do NOT use function evaluation mode with Adams/Controls, so I think that that idea is ok. I'm wondering about your comment on this..
     
    Thanks,
    Kent

    Hello Kent,
     
    yes you are right I am trying to simulate a cantilever beam in a discrete mode cosimulation. I made an experiment and now I want to model the beam and a force (that is why I use Matlab) but unfortunately the beam I am trying to simulate is pretty long. Thus it is not possible to model it trough DISCRETE FLEXIBLE LINK with an accuracy that is good enough for me, (I only use the student version and there is a limit on 20 parts). So it would be nice if there is a possibility to get the cosimulation with the FE_PART working.
     
    Thanks

    Hi Alex,
    Unfortunately I don't think there is a *current* solution to have the FE_PART working with co-simulation! I have logged an enhancement report on this topic ('Make FE_PART work with discrete co-sim') for the future.
     
    I think your best bet currently is to use the discrete flex link in a *commercial* version of Adams.. wish I had better news, good luck,
    Kent
