Comments

  1. This keyword maps to /MAT/LAW83, /FAIL/SNCONNECT, and /PROP/TYPE43 (CONNECT).
  2. The material is fully compressible in the vertical direction from solid element face 1 to face 2.
  3. The tension stiffness is in the vertical direction and shear stiffness is perpendicular to the vertical direction.
  4. The option “_TITLE” can be added to the end of this keyword. When “_TITLE” is included, an extra 80 characters long line is added after the keyword input line which allows an entity title to be defined.
