How to apply torque/moment.

Recommended Posts

Hi,

 

I have created a block with Hexa elements and shell elements with rigid body at 1 mm distance from block. please find attached image file.

 

Block is going to impact over rigid shell with 50 N-mm of torque.

Type-7 contact is defined between block and shell elements. 

 

problem is solving without error but in contour plot rigid body moved near to block and block is swinging. as shown in below picture.

is there any method to define torque in Radioss?

 

 

Thanks and Regards

Hi Narasimhamurthy,

Torque can be applied by selecting the concentrated load from the BCs Manager and selecting the direction plane (XX, YY or ZZ).

Hi Narasimhamurthy,

The model setup seems to be fine and the model behavior is also as defined. Can you please elaborate the problem you are facing.

I just moved the rigid body and increased the CLOAD to review the behavior and the same is attached along,

Hi Narasimhamurthy,

Please find the attached image. The block is moving in the same direction as defined.

Hi Narasimhamurthy,

Now I got your query.

Keep the ICOG of the rigid body to 3 and run the analysis.

Yes. ICOG=3 in the /RBODY keyword should be the solution.
