1.	Compatible with 2D Analysis only (/ANALY). Material must be defined as an ALE (/ALE/MAT) or EULER (/EULER/MAT) material.

2.	and are initial percentages of mat_ID1 and mat_ID2.

3.	Material identifiers mat_ID1 or mat_ID2 cannot be used with material Law 11.

4.	Only material type Law 20 can be frontier to the material Law 20.

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.
