Segmentation Violation

Altair Forum User

Hi,

 

I'm trying to run an implicit nlgeom analysis and keep running into the same Error Termination:

 

*** ERROR # 4002 ***
 Running RADIOSS engine, 1 ERROR and 0 WARNINGs have been detected.
 They are listed below.

 ENGINE ERROR:
  ** ERROR : ABNORMAL END
       +=============================================================+
       |          Segmentation Violation                             |
       +=============================================================+
       | TRACE BACK :                                                |
       +=============================================================+
       | +  RADIOSS ENGINE
       | +   SOLUTION PHASE: Processor=    1/   16
       +=============================================================+
 
  NLGEOM subcase        1, engine finished

 

The analysis contains 2D and 3D elements and two contact definitions. But the same error occures when I just use 3D elements.

Can anybody help me solve my problem?

 

Thanks in advance!

Hi Niwi,

 

Please share the all .out file(s) (you will also see <filename>_0000.out and _0001.out files in working directory) to check what the problem is.

Somehow I'm not permitted to upload the files.

Hello everybody,

 

I'm still struggling with my analysis. Any ideas so far?

 

Thanks in advance,

Run it from a local drive instead of a network drive if that is what you are doing,

 

Try and reduce the element number if it is too large,

 

check the out file for more information about the error etc

I did run it on a local drive and got the same Error message. The .out file dowosn't deliver any new clues, either.

 

It seems I'll have to try and reduce the model as much as possible.

Hi Niwi,

 

I think the error is due to the table definition. 

 

Please have a look at the comments for TABLED1 entry and change the table accordingly.

Hi,

 

I don't really get the mistake. x_i is allways ascending and there are no discontinuities, since y_i doesn't have to be either continually ascending or descending.

But I guess I could try to work around this problem by using CONTNLSUBs.

 

Thanks

Nothing I tried did anything. The Error still occurs.

Do you have any other ideas?

Hi Niwi,

 

So I tried working on your model using HyperCrash/RADIOSS and found that there are lots of duplicate shell elements.

 

could you please check this?

 

I tried to delete the duplicates but these duplicate elements have the contact surfaces on them which requires re-modelling.
