added interface routine for Marc2008r1
this includes two files: concom_f90 and creeps_f90 so you either create links of that name to the new files concom2008r1 and creeps2008r1 or rename copies of those files accordingly

! 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!)
|
||||||
|
! - in case of ddm a symmetric solver has to be used
