Comments

  1. For structural problems, MID may reference only a MAT1 material entry.
  2. In case of plasticity problems, MATS1 can be referenced with the same ID as MAT1 in small displacement and large displacement nonlinear analysis. The plasticity behavior is considered only in the axial direction, and the torsional behavior remains elastic.
  3. For heat transfer problems, MID may reference only a MAT4 material entry.
