How to resolve the crash during simulation?

[SUMAN KUMAR]

Dear all,

I frequently get this kind of error where the program is crashed and prematurely closed. For your reference, a screenshot is attached. Further, for similar models, the program is normally terminating; however, for a few, it is crashing. Are there any possible suggestions/guidance/ remedial measures available? This will be of great help.

Thank you,

 Suman Kumar

Dear Suman,,

 

Access violation 157 is usually due to some kind of memory read/write error. For this

situation, I would suggest contacting your distributor or LSTC support. Of particular

importance, is, please send the model to debug.

 

Sincerely,

Dear Suman,

That's a mysterious error that many users encounter. Therefore, it is not possible to guess where the problem might be without having the story of your problem. I suggest you first tell the story of your model: I am sure some users ın the group have already experienced this error. I also had this error a couple of times. My suggestion is to focus on your contact algorithms since that was the case when I got this error. To solve this kind of problem, I always create simple sub-models to identify which key card causes the problem. After the identification, you can work more on the root cause. That is not an exact answer maybe but I hope it guides you. 

Kind regards

Kagan
