Remark 1
The method in the figure below provides a consistent and reliable way to assign material IDs to *ELEMENT_SHELL_COMPOSITE layers using *MAT 249 as the target material model. The method reduces the number of maximum possibilities by regulating material IDs.
Figure 5.1: Illustration of Method to Assign Individual Composite Layer Integration Point Material IDs in *ELEMENT_SHELL_COMPOSITE Keyword
The material ID is limited to eight digits. The initial three digits indicate that the target material model is *MAT 249. The following two digits are for the clustering method. Finally, the last three digits represent fibers, since *MAT 249 supports up to three fibers per integration point (IP). The fiber digits indicate the position of the found beam element PIDs declaration as source part ID in mapping command file. An example is provided in Figure 5.2: Example of Method to Assign Material IDs. If an element has less than three fibers, this method assigns 0 to preserve the eight digit material ID.
