Comments

  1. This keyword maps to a New-Hookean incompressible material /MAT/LAW42 with Poisson's ratio = 0.463.
  2. 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.
