Error of incompatible kinemtatic conditions and model inconsistency
Hello,
I am trying to simulate a torsion case in radios block 110 format using hyperworks 12.0
I am getting errors for incompatible kinematic conditions and model inconsistency. The screenshots for the same are attached here.
Kindly let me know about the solution.
Thank you.

Hello,
Thank you for your quick reply.
Material type is elasto plastic and material card image is Johns_Zeril.
Yes I have assigned PART card to the components. I have made two more components each one of which contains a rigid body. Is it necessary to assign them also PART card image . I have not done so as they are rigid and will not make any effect with material or properties.
Hi Gopal,
So you have a component with mesh and you card edited and made is it as rigid. Is my understanding correct?
That is the correct way. You have to give the component a PART image and make assign property and material.
Here is a tip and trick which tells how to make a structure rigid: http://www.altairuniversity.com/wp-content/uploads/2015/04/Make-a-structure-rigid-for-RADIOSS.pdf
Hello,
I first made a component without any card image and other properties. The made that component as current and then made rigid body element using 1 D rigids and thus this element goes into the component.
In the images attached earlier , it is showing that an element is missing but on checking with the find option using ID I can see the element.
Hello,
There is no error coming with RBE element.
I have send the starter and engine files of the simulation from email ID: gopal.singh@icat.in
Hi,
Thank you for the support.
I was able to run the simulation. For torsion I have used the boundary condition named: initial velocity around an axis applied to rigid body node. There was no option of making any curve for the function. Thus will it be taking a constant angular velocity throughout the simulation. Kindly let me know for the same.
Hi,
I checked in the boundary conditions manager but could not find imposed velocity about the axis. Initial velocity about axis is available which I have tried but the results were not as expected. Actually I want to apply an angular velocity to nodes on one side of the beam which is basically the torsional load acting on the beam and keeping the other end of beam fixed.
Hi Gopal,
I have created a new topic for your query. Please create a different topic for every new query.

Hi Gopal,
could you please let us know what is the material and property are you using?
Also, please check whether /PART card is assigned to component(S) or not.
