The sd_cham_master data structure is produced by the AFFE_MATERIAU operator. It contains an « essential » and mandatory map containing the name of the materials (sd_mater) affected on the mesh cells.
For quick access to material characteristics in the te00xx routines, the concept of « coded material » (sd_mater_code) was introduced.
As a result, it was necessary to create the sd_cham_mater_code, which is a map in which materials have been replaced by « coded materials ».
The sd_mater and sd_mater_code data structures are described in [D4.06.18]
