  2. Load on Rigid body

    How to convert part into Rigid body ? and apply load on rigid body? Regds, Arul
  3. RIGIDS

    If I want to connect two components can I use components to select in the rigid panel? Thanks, Datta
  4. RIgid body imposed velocity

    Hi. I've tried to build rigid body and the extra nodes. The rigid body is placed CG of a car. The extra nodes are placed in several nodes on fixed position of a seat inside a car. I make imposed velocity, with its rigidbody, x translation (in my case translate backward), and LCID i integrate from acceleration-time history. I try to crash the seat into the box. However, when i look the result animations, only rigid body and the extra nodes moved instead of the whole seat Could i move the whole seat by only create imposed velocity of rigid body? Thank you for your help. Attached the model of the seat picture
  5. Rigid Body Mesh

    Hi everybody I would like to create a rigid mesh on the surface of a body, because i need a rigid body, for which are not calculated stresses neither strains. Could i mesh this surface using "rigid body mesh" panel in automesh panel? if it is the way, the mesh created will be used just to compute other things like interfaces reactions or others, and the mesh created will be completely rigid ... i'm i wrong? thanks
  6. Hypermesh to Ansys

    Hi, I'm quite new for using Hypermesh. I've an assembly of 3 components. I've tetrameshed each component. After meshing I just exported the mesh in a .dat file. When i use this mesh in Ansys WB all the components are flexible, What should i do to change everything to Rigid?? If i change it in Ansys then its asking for a remesh. Could someone help a little. Thanks, Vishnu.
