Fail in Initial condition analysis at beginning of co-simulation

Hi all,

I'm running a co-simulation between ADAMS 2017 and Matlab r2016b, using a standard step steer maneuver. As soon as I start the co-sim from Simulink I get the error message that the initial condition analysis fails.

Looking at the "*_controls.acf" file, the sim/init is the latest command there but the only way I can make the simulation correctly running is to replace this entry with the following:

control/routine=abgVDM::EventRunNext, function=user(0)

I can understand now that the initialisation process is different when running ACAR vehicle models with driver rather than without it (or AVIEW models), but shouldn't the AControls be able to differentiate between the use cases and run the proper command sequence?

Of course I may be missing something in the process that would turn back the problem to the user :) rather than to the software. In this case, I would appreciate if someone can tell what I'm doing wrong.

Many Thanks,

Giuseppe.

How did you export the model for the co-simulation? The procedure is very different for A/Car and A/View.

You can't use the Controls -> Export with A/Car.

To export for co-simulation with A/Car you should do this:

Load the controls plugin

Run any analysis with "Files Only".

That will export the proper files, including an acf with the correct syntax.

Hi JSlatten,

I used the Mechatronics plug-in to build up the I/O and the Control System. Then I ran a simulation as files-only and finally used the amech pop up window with then new generated .adm to generate the proper .m file. I think all standard things.
