Covergence Study for Solid component and lattice component

Hi everyone,

I want to do a convergence study for two components ( 1st Solid component and 2nd lattice component) I have attached the pic of my components together in one picture for your reference.

First I want to do a mesh convergence for lattice to find out optimial mesh for the component with the same E and density values , Similarly I have to do a mesh convergence for solid component same like lattice.

My Question is  after finiding the mesh convergence study what I mentioned above I have to make a covergence study regarding E modulus, In order to tell how much the E has to be reduced regarding the density of Lattice component to reach same behaviour of solid component. How I can proceed to do convergence study regarding E modulus that the LS block and Solid-block have same behaviour. A help would be really appreciated. Anticipating a good response for experts. Thank you .

 

Kind Regards,

Muthu.

    Hi,

     

    One way is to change E value manually and check the results.

     

    or

     

    Do a size optimization with E as design variable.

    @Prakash Pagadala  Hi Mr.Prakash , I have a question , How can I create a rigid plate as bottom (all dof locked) and rigid plate as top to apply force (all dof locked, except vertical translation) in a simple cubic model . Should I just constraint bottom surface to ( all dof locked ) and top surface to ( all except vertical ) ?  how i can do this rigid plate thing on my model , can you help me ? thanks in advance .

     

    Kind Regards,

    Muthu .

    If you are using OptiStruct linear static analysis type, provide a high E value to make the component rigid.
