How to define a body as rigid in hypermesh ?

(For example if i simulate 3 point bending i need to define the fixture pins as rigid)

<?xml version="1.0" encoding="UTF-8"?>

bind nodes of the pins by RBE2 => pins will be 'rigid'

Hi,

 

As Tinh said, you can use RBE2 or if you have a shell or solid mesh what you can do is define a material is very high youngs modulus. 

 

Stiffer materials have higher Young's modulus value.

Hi,

 

I am in a fix right now. I have no idea how to assign the RBE2 to my shell elements. Could you elaborate more on the method? I did it like this:

 

Properties --> Rigid section --> Rigid body

 

I exported the elements into Abaqus and the error came out saying I must have a shell section before I assign rigid properties to the elements. How can I do this?

 

Thanks in advance for your help and advice.

Hi,

create a new component named 'RBE2'

enter panel 1D>rigid select master node as 'calculated', slave nodes=>select nodes of shell elems => create

Hi Tinh,

 

Thanks but I still don't understand it. So I should create a new component and name that component 'RBE2'? Then what will happen to my shell model? How can I assign it as a rigid body?

 

Sorry but thanks a lot for your help.

 

Best,

Hi,

the name is not important, just for good organization

the RBE2 elems connect nodes of your shell model and make those nodes fixed to each other, so the shell model will never be deformed, it's rigid
