SettingDescription
Type Select the type of support or boundary condition.
  • Free — No restrictions on any direction
  • Pinned — X, Y, and Z are fully restricted, and RX, RY, and RZ are not restricted at all.
  • Partial — There is some combination of restricted and free directions other than that which qualifies for Free, Pinned, or Fixed.
  • Fixed — All directions are fully restricted.
X, Y, Z Set the restrictions for the movement of the node for translation X, Y, and Z (the node changing coordinates in those directions).
  • None — No restriction.
  • Partial — Partial restriction. Enter the degree of restriction. A zero degree of partial restriction is the same as None.
    • Kx, Ky & Kz – Appears when the support Type is set to Free or Partial and the translation Restraints are set to Partial. The field is provided for specifying a spring constant.
  • Full — Full restriction.
RX, RY, RZ Set the restrictions for the movement of the node for rotation RX, RY, and RZ (the node rotating in those directions).
  • None — No restriction.
  • Partial — Partial restriction. Enter the degree of restriction. A zero degree of partial restriction is seen by the software as the same as None.
    • Krx, Kry & Krz – Appears when the support Type is set to Free or Partial and the translation Restraints are set to Partial. The field is provided for specifying a spring constant.
  • Full — Full restriction.
