!********************************************************************
|
||||
! 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!)
