Defining displacement constraint in lstasc

    • shk1048

      In my case i have to restrict the displacement of the design part to 70mm in -z direction.
      Is it the correct way of defining the displacement constriant with minimum value as in the image

      The contraint definition is correct but note that for nodout option, you have to specify a node id and displacement of that particular node is extracted. Since you are interested minimum displacment of the entire part, use d3plot option instead of nodout and specify part id(s). If you have a shell layer on top of design part, extracting min displacement of this shell part might be better than using design part.
