Comments

  1. Compatible with 2D Analysis only (/ANALY). Material must be defined as an ALE (/ALE/MAT) or EULER (/EULER/MAT) material.
  2. α1 and α2 are initial percentages of mat_ID1 and mat_ID2.
  3. Material identifiers mat_ID1 or mat_ID2 cannot be used with material LAW11.
  4. Only material type LAW20 can be frontier to the material LAW20.
  5. Activating flag for incoming material control (ICi = 1) enables filtering incoming material mat_IDi.
  6. Activating flag for discrete filling (IDISCRETE = 1) enables old initial filling (version 10.0.3 and prior) for all Bimaterial laws in the input file. Partial filling for other bimaterial laws is not taken into account.
