The simulink simulation slows down when I use a switch, it does not give any error but it stays at .5 second indifinitely!

I am trying to select one output from two blocks depending on certain conditions, and then forward that signal as input to another block, but the simulation almost comes to a standstill and I also get no error. What could be the problem?

You have not chosen the correct solver for your application.

You will need to use Simulation->Model Configuration Parameters->Solver to adjust your solver types, tolerances, and/or step sizes to account for the stiffness of the switch.

Thanks dude, this is working

The solution of changing the solver parameters didn't work for me, but I found a workaround :

instead of using the manual switch block, I use the signal compare switch connected to a constant controlled by a push button.

I think the manual switch block is simply broken so I will avoid it in the future.
