Simulink rapid accelerator slowly filling HD

I am running an optimisation problem which requires to run a Simulink model several times to find the minimum of the cost function. The Simulink model is set up in rapid accelerator mode and run in parallel on different cores. The problem is that Matlab is slowly filling the hard drive with temporary files (.dmr files in ..AppData\Local\Temp). Is there any way I can avoid Matlab from building up these massive files?
