Forced displacement in segment normal direction

    • young

      Structure: Cylindrical structure
      element type : solid element

      Material : MAT24
      Loading condition: Define displacement in the radial direction or in the normal direction of the segment of the solid element

      I wonder how to define the above load among ls-dyna keywords.

      And here is an example model:
