failed assertion in b:\matlab\​toolbox\st​ateflow\sr​c\stateflo​w\utils\ob​ject.cpp at line 2870: object[id]!=NULL (Matlab 2014a)

Hello all,

We have an assignment to work with the auto-transmission model (sldemo_autotrans) and make it a more complex one.

We have added cruise control, rpm control etc.

My partner have done a lot of the work on his computer and now that I am trying to run the model on mine I get the following output:

failed assertion in b:\matlab\toolbox\stateflow\src\stateflow\utils\object.cpp at line 2870:

any1 got an idea on what to check?

[Francisco Rodriguez]

Hi,

I've the same problem. Somebody have any idea to solve this problem?

Thanks.

[zuowen li]

I've the same problem.

[Von Shefton]

Did anyone figure out how to resolve this problem within R2014a?

[Walter Roberson]

Probably the following is a different error, but it is worth checking as a possibility: https://www.mathworks.com/matlabcentral/answers/274135-mission-on-mars-2016-simulink-failed-assertion-after-the-first-run#answer_246910

Answer 1

[xiefuhong]

I have the same problem in the past few days and it is solved now. My solution is that I delete all side files, such as the .slxc files and the "slprj" folder, and only keep the source files such as .m scripts and Simulink model. When I restart the MATLAB again, the problem is fixed. I hope this can help you.

Answer 2

[Alexander Kramlich]

Same problem here (2017a). Why is nobody answering that?

Answer 3

[越 商]

Hi,my version of matlab is2019b, I also have this question,First, I think it's a bug in mtlab,but I use my model in another computer, My model also can not run......That's drives me crazy....in the end, I find my solution, the TestScenarios(such as the model of include_ACC,include_AEBS files,do not edit casually) before you edit it,remember copy this files in case of error happen..

Answer 4

[Aman Jacknoon]

I have just faced the same problem. I copied my project codes and simulink folder that was working fine in a flash drive to run it in another computer, and it gave me the same error.

I copied the source code again using the same flash from my laptop to the same computer and it worked well.

My interpretation to this, is that it seems as if copy of the code to the flash was not complete in the first time.

I am glad that this problem is resolved.

Answer 5

[Mahin Mirshams]

I got this error when I was saving my diagram in simulink. I just simply copied my .slx file into another directory and then opened it again. It just worked! I guess it might be caused by a crash on the application and miss data replacement in the workspace or the run configurations.

[Somasundaram kowsik kumar]

i did the same thing , but i m getting the same error!!

[Mahin Mirshams]

try deleting all files( except for the .slx one) and change the directory( maybe is sth wrong with the name:-?).

Answer 6

[Ondrej Kamensky]

I had similar problem / error when I was trying to compile my model for NI Veristand 2020 in Matlab 2017a:

failed assertion in b:\matlab\toolbox\stateflow\src\stateflow\cdr\cdr_rtw_interface.cpp.....in some line.....

what was strange because I was not awared that I am using any stateflow feautures.

Strange was also that I was able to execute the model locally in simulink. I was not able just to compile / build DLL.

For me solution was in Simulink Configuration Parameters, under Code Generation / NI Configuration I had option "Disable all Stateflow signals". So I disabled it and then I was able to compile model and build DLL library.

But probably this will be not solution for somebody who intend to use Stateflow.

Answer 7

[Ahmed]

I cleared everything and restarted matlab and then it worked.
