USING RIGID PROPERTY AND AMS AT SAME TIME

Altair Forum User

SIR, 

I have encountered an error saying id, RIGID MATERIAL LAW cant be used along with AMS- Advanced mass scaling, Try modeling as \rigidbody, but i havent found any rigid body except 1d rigidss, can you guide me through this as i am doing imposed displacement problem.

Thank you for your proactive approach of answering..

Hi,

Please provide the .out file containing the error.

Also you can go making the complete component as RBODY and make IcoG 2: This also makes the same thing as Rigid material law. Also there are certain limitations with rigid material law of which is with AMS.. I have attached the image for reference.

Hi Ramakiran,

Instead of /MAT/RIGID use /MAT/ELAST (Mat Law 1)  and try running the analysis.

Hi Ramakiran,

Go to Utility>Rbody Manager, select the Rigid Body and card edit the same and you can find the option to change ICoG.

You can see the steps in this webinar at http://www.altairuniversity.com/conceptual-design-of-a-3-wheeler-motorbike-crash-box-analysis/ (Select Rigid Body video from the list)

Hi.

Can you clarify the problem statement. As the body is rigid , it is not going to absorb energy and if you are impacting it, it is expected to rebound . Is this the scenario?
