Hi,
I am trying to get the current simulation status of my simulink model (initializing,running,paused etc.) by using an event listener. I need this because the model takes a long time to start, and I want to show the current status in my GUI. But I dont have a clue, how to set the "blk" parameter, because I want to access the model itself, not a block within the model. So, the following doesnt work:
blk = 'model';
event = 'PostOutputs';
listener = @sim_status;
EventListener = add_exec_event_listener(blk, event, listener);
Does anyone know, how to solve this? Thanks.

You can Model Callback functions to capture the simulation status.
Some simulation related callback functions are:
  • InitFcn
  • StartFcn
  • PauseFcn
  • ContinueFcn
  • StopFcn
Also you can read simulation status of a model using below command anytime. It will return string — {'stopped'} | 'updating' | 'initializing' | 'running' | 'paused' | 'terminating' | 'external'
get_param('myModel', 'SimulationStatus')

Hey Thanks you Tabrez, This is exactly what I did. I was using them for other purposes, but added one more line of code to findobject on GUI and update the status string in it. But thank you once again Tabrez.
