DESCRIPTION |
UM |
N_MAT |
integer |
number of materials |
- |
MAT_HEADER[N_MAT] |
character |
identification string (skipped by ATLAS) |
- |
MAT_TYPE[N_MAT] |
integer |
material type |
- |
MAT_IPAR[N_MAT,NI_MAT_TYPE] |
integer |
integer parameters of the material ( the size NI_MAT_TYPE depends on MAT_TYPE) |
- |
MAT_RPAR[N_MAT,NR_MAT_TYPE] |
real |
real parameters of the material (the size NR_MAT_TYPE depends on MAT_TYPE) |
- |
N_MAT
MAT_HEADER[1]
MAT_TYPE[1]
MAT_IPAR[1,NI_MAT_TYPE]
MAT_RPAR[1,NR_MAT_TYPE]
MAT_HEADER[2]
MAT_TYPE[2]
MAT_IPAR[2,NI_MAT_TYPE]

- Example [
MAT_TYPE = 1] : this example defines two isotropic linear elastic materials :
2 ! N_MAT
'mat1' ! MAT_HEADER[1]
1 ! MAT_TYPE[1]
1 ! MAT_IPAR[1,NI_MAT_TYPE]
1.0d0 0.25d0 1.d0 1.d0 1.d0 0.d0 0.d0 ! MAT_RPAR[1,NR_MAT_TYPE]
'mat2' ! MAT_HEADER[2]
1 ! MAT_TYPE[2]
1 ! MAT_IPAR[2,NI_MAT_TYPE]
1.0d0 0.25d0 1.d0 1.d0 1.d0 0.d0 0.d0 ! MAT_RPAR[2,NR_MAT_TYPE]
