Is it possible to do a batch run with a Simulink model in rapid accelerator mode and linked to a data dictionary without rebuilding the target every iteration?

I am changing a variable within the data dictionary for each run. I find that if I set 'RapidAcceleratorUpToDateCheck' to 'off', my model does not seem to update with the changed data dictionary. It does work correctly if I leave 'RapidAcceleratorUpToDateCheck' to 'on.' However, for the latter case that works, when I calculate the checksum each iteration, they appear to be identical. Does this not suggest that I should not have to rebuild?

Hi,

Yes, this is expected behavior. Data dictionaries are not tunable parameters and if you select this option to be 'off', it will be faster as there won't be a rebuild but does not satisfy the current workflow.

For applications of this option in parallel simulations, see this:
