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

If you're running in interactive mode, you can add a few lines to the end of the CMD file to turn off RES file creation,

output set results model = .model_1 create = off

But the other thing that'll slow down interactive mode is having "Update graphics display" checked. I like to manually turn it off, but it looks like you can add another line to do this:

simulation single set update = "none"

Lastly, you could instead choose to trim down the RES file to pretty much just the requests by adding this line:

output set results formatted = off xrf = on accelerations = off applied_forces = off displacements = off reaction_forces = off velocities = off data_structures = off system_elements = off linear = off floating_markers = off tire = off friction_summary = off comment = off contact_incidents = off node_incidents = off
