How to reduce simulation data output using co simulation with Matlab

Hello!

I am running a rather complex Adams model in co-simulation with Matlab Simulink with high output sample frequency of min 4 kHz over a couple of seconds. Thus the results file is getting pretty big and maybe even slowing down my Analysis. As I have a separate request file with the results of interest I wonder if I can set a variable for that only the request file (and optionally the .gra) will be written?

Maybe someone has some experience with this. Would be nice to know. Thanks!

Kind Regards

Thanks for your replies!

The reason I was wondering was that in the Adams model I did not set option to output .res, .req or .gra.

When I did the plant export of the Adams model and import to Simulink I could only set a name for the results of the simulation (in the Simulink block), not which kind of export I like to chose.

The answer was actually easier than I thought:

In the exported .adm, there needs to be the command.

OUTPUT/

, REQSAVE

, GRSAVE

Yet I cannot tell if that speeds up the simulation, but my feeling is that it does not.

Kind Regards
