Parent Command
all second-level commands in block > PARAMETER referring to a material name

Subcommand
all fourth-level commands in block > PARAMETER

Description
This command identifies material names (TOUGH2 variable MAT). Most parameters refer to a particular material, i.e., they are specified in TOUGH2 in block ROCKS. Rock types are designated by a five-character code name. Blanks in the material name must be replaced by underscores (e.g., if MAT in TOUGH2 reads 'CLAY ', mat_name must read 'CLAY_'). If multiple material names are provided, the estimate of the corresponding parameter will be jointly assigned to all listed materials. If distinct parameters are sought for each rock type, separate >>> MATERIAL blocks must be defined. Default properties (i.e., for parameters referring to TOUGH2 blocks PARAM.4 and RPCAP) can be selected either by >>> DEFAULT or >>> MATERIAL: DEFAU. If the substring [islotb-islote] (default: [4,last]) of the last mat_name is an integer, a sequence of iplus material names can be generated. The following two command lines are thus identical:

>>> MATERIAL: BOREH ROC10 ROCK1 +4 [5-5]
>>> MATERIAL: BOREH ROCK1 ROCK2 ROCK3 ROCK4 ROCK5 ROC10
