Simulink Post Sim Function

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.

[Ajay krishna Vasanthakumar]

This will trigger only when we save the model.I need to change the dialog parameter immediately after termination

Thanks for your reply :)

[Fangjun Jiang]

Why "i am unable to do it in StopFcn"? StopFcn is ran after the simulation stops.

[Ajay krishna Vasanthakumar]

In stop function we can change the constant value and gain value but not other parameters :(

[Fangjun Jiang]

I am curious. What parameter?

[Ajay krishna Vasanthakumar]

i am not able to change the while loop - show iterator port parameter.

[Fangjun Jiang]

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.

Thanks alot for answering

[Fangjun Jiang]

So, were you able to acomplish this task using setpostsimfcn?

[Ajay krishna Vasanthakumar]

unfortunately iam working on R2016b.i have the to put the work on hold

[Ajay krishna Vasanthakumar]

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

[Fangjun Jiang]

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

Thanks a ton Fangjun =D
