Job errors

(OP)
Hi,
I modelized an impact between a sphere and a plate.
So , I created the job et I submitted.
Therefore, after moments, I looked at the monitor and I noted that I had 13 fatal errors like:

-NODE SET ASSEMBLY__PICKEDSET30 HAS NOT BEEN DEFINED

-A BOUNDARY CONDITION HAS BEEN  SPECIFIED ON NODE SET ASSEMBLY__PICKEDSET30 BUT THIS NODE  SET IS NOT ACTIVE IN THE MODEL

-NODE SET ASSEMBLY_PLAQUE-1_PLAQUE-1-REFPT_ HAS NO MEMBERS AND WILL BE IGNORED.  NODES DEFINED IN THIS SET MAY HAVE BEEN DELETED
 BECAUSE THEY WERE NOT CONNECTED TO ANY ELEMENTS.

-NODE SET "ASSEMBLY_CENTRE DE L'IMPACTEUR" HAS NOT BEEN DEFINED

Can you tell me how to fix these errors please?

Cordially,idate.

RE: Job errors

(OP)
Thanks a lot. I fixed this problem but now I have one error that I don't understand at all.

This error is:

CONTACT PAIR REFERENCES SURFACE/NODE-BASED SURFACE/ANALYTICAL RIGID
SURFACE ASSEMBLY__PICKEDSURF17 BUT THIS SURFACE/NODE-BASED SURFACE/ANALYTICAL RIGID SURFACE HAS NOT BEEN DEFINED OR THIS
SURFACE IS DEFINED ON THE COLLAPSED FACES

Can you tell me how to fix this little mistake in my last modeling?

Cordially, idate.

RE: Job errors

It's better to define surfaces with a name than to just pick them off the screen. However, you can check the surfaces in your contact definitions by editing the contact interaction and checking either the master or slave surfaces.

So I have to create surfaces in each parts, assign these surfaces, then I have to modify the master or slave surfaces in "contact interaction" with the new surfaces created , do I understand well?

RE: Job errors

(OP)
Is there any chance whatsoever that I created my sphere with discrete rigid body and not analytical rigid body?

I made my sphere like that because with analtical rigid body, I couldn't revolved an arc of 180 degrees.

 

RE: Job errors

(OP)
Now I have not errors anymore, just warnings.
Therefore, when I submit my job, it's submitted but it's never completed.

What can be causing this?

Thanking you in advance

Cordially, idate.

Hi Rob,
the problem may be that I used only two steps when my modeling should be three, right?
If so, why should I do three steps?

Thanks

Cordially, idate.

RE: Job errors

Valid analyses of this type aren't really appropriate for student edition as your are limited to 1000 nodes.

RE: Job errors

Good point Rob. Looks like he's not concerned about deformations of the sphere, so he can use all 1000 nodes on the wall. When you mention increase the steps, what do you mean? I think rob was suggesting you increase the step TIME, which is the length of time of the simulation.
