Errors about degree of freedom 11

Errors about degree of freedom 11

Errors about degree of freedom 11

(OP)
Hi friends, I'm new here and also as abaqus users. I try to learn about the software by following some tutorial from youtube. Included this tutorial https://www.youtube.com/watch?v=UCUdsn8bIwY about impact bullet, because i need to do my final project about bird strike.
I follow the tutorial precisely but this is what i've got:
errors:
Degree of freedom 11 and at least one of degrees of freedom 1 thru 6 must be active in the model for *dynamic temp-disp. Check the procedure and element types used in this model.
warnings:
Both the transition and melting temperatures are zero. Temperature dependencies are suppressed

Both the transition and melting temperatures are zero. Temperature dependencies are suppressed

The option *boundary,type=displacement has been used; check status file between steps for warnings on any jumps prescribed across the steps in displacement values of translational dof. For rotational dof make sure that there are no such jumps. All jumps in displacements across steps are ignored

Degree of freedom 4 is not active in this model and can not be restrained

Degree of freedom 5 is not active in this model and can not be restrained

Degree of freedom 6 is not active in this model and can not be restrained

Degree of freedom 5 is not active in this model and can not be restrained

Degree of freedom 6 is not active in this model and can not be restrained

Degree of freedom 5 is not active in this model and can not be restrained

Degree of freedom 6 is not active in this model and can not be restrained

Degree of freedom 4 is not active in this model and can not be restrained

Degree of freedom 6 is not active in this model and can not be restrained

Degree of freedom 4 is not active in this model and can not be restrained

Degree of freedom 6 is not active in this model and can not be restrained

Can you guys help me out? Thx before.

RE: Errors about degree of freedom 11

Hello!
Sounds familiar... are you using elements that can handle temperature? "Normal" structural elements can't I think.

/S

Why familiar?? I'm not sure. I just follow the instruction from the video.
I think i'm not doing something about temperature.
"Normal" what?

RE: Errors about degree of freedom 11

Familiar to me since I have also had this error when I did a *dynamic temp-disp.
By normal I mean a structural element, default settings in CAE.
In the video, the guy makes a Dynamic Explicit step (no temperature).

Your error, "Degree of freedom 11 and at least one of degrees of freedom 1 thru 6 must be active in the model for *dynamic temp-disp." leads me to believe that you have a different step type from what you want.

Hope it works out. :)
