Hi everyone, I am using Simulink 2014b for a project which admittedly has a lot of subsystems and takes the Ramp source as an input. I have to run the simulation for 10 s. The simulation is slow (takes around 20 min!) but the greatest problem arises when the simulation ends and gets stuck at the "Terminating" phase. If I try to stop the Simulation, the MATLAB hangs and I have to end it from the Task Manager (all the data is lost inevitably!). I don't get what the basic issue is as my system is pretty adequate (16GB RAM, Core i7, 1TB hard disk) and the simulation runs fine, albeit slowly, for step inputs! Any help would be greatly appreciated! Thanks.
