Hello Friends,
is there any way to kick start a custom function post simulation ?
What i want to do is i am changing a block paramter in init function ,after simultion i want to change the block paramter again to original
i am unable to do it in StopFcn.I am using matlab 2016b
Thanks in advance

Try the PostSaveFcn.

This will trigger only when we save the model.I need to change the dialog parameter immediately after termination
Thanks for your reply :)

Why "i am unable to do it in StopFcn"? StopFcn is ran after the simulation stops.
In stop function we can change the constant value and gain value but not other parameters :(

I am curious. What parameter?
i am not able to change the while loop - show iterator port parameter.

You are right. It is odd that Simulink complaints "Cannot change number of ports while simulation is running" but the callback is "StopFcn". It is meant to run the command "after" the simulation stops.
Make an example and send a request to the Mathworks tech support. Ask their explaination why you can change other block parameters but not this one in "StopFcn". You can certainly do this using a separate script. Ask if they have a solution if you have to use a callback.
sure Fangjun :).From 2017a we have a function called setPostSimFcn but prior to that we donot have any option.

So, were you able to acomplish this task using setpostsimfcn?
unfortunately iam working on R2016b.i have the to put the work on hold
Hey Fangjun
have you used this function "SimCustomTerminator" ?
we have the simulink inbuilt function but i dont know how this works.
if you can share your knowledge on this, i can attain the possible solution !
Thanks

No. Never used this property. I tried it in R2016b. It didn't do what you are expecting.
