  1. 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.
  2. Hallo Everyone, I have created an lattice structure unitcell (BCC) of 1mm x 1mm x 1mm in CAD with that I created a whole component of 10mm x 10mm x10mm so there are 1000 unit cell in my component. I imported that component into hypermesh and it shows 1000 individual components in the model section. I want to analyse the component by applying load on the top face by constraining all the dof at the bottom and do the convergence study ( mesh refinement) . My questions are 1) how can I combine or merge all other component 1000 individual components in to a single whole as one component, I think it would be better for meshing and further analysis. ( I have attached the file for your reference please take a look) 2) How can I create a rigid plate on the bottom for locking all the dof and also rigid plate on the top for locking all dof except vertical translation for applying loads ) Thats all my questions , Please take a look on my component . Anticipating a response. Thanks in advance. Kind Regards, Muthu. lattice.stp
