!********************************************************************
|
|
! Usage:
|
|
! - choose material as hypela2
|
|
! - set statevariable 2 to index of material
|
|
! - set statevariable 3 to index of texture
|
|
! - choose output of user variables if desired
|
|
! - make sure the file "mattex.mpie" exists in the working
|
|
! directory
|
|
! - use nonsymmetric option for solver (e.g. direct
|
|
! profile or multifrontal sparse, the latter seems
|
|
! to be faster!)

! CAUTION : Due to calculation of the Deformation gradients, Stretch Tensors and
