! Material subroutine for MSC.Marc

! MPI fuer Eisenforschung, Duesseldorf
!
!********************************************************************
! Usage:
! - choose material as hypela2
! - set statevariable 2 to index of homogenization
! - set statevariable 3 to index of microstructure
! - make sure the file "material.config" exists in the working
! directory
! - make sure the file "numerics.config" 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 (domain decomposition)a SYMMETRIC
! solver has to be used, i.e uncheck "non-symmetric"
!********************************************************************
! Marc subroutines used:
! - hypela2
! - plotv
! - quit
!********************************************************************
! Marc common blocks included:
! - concom: lovl, ncycle, inc, incsub
! - creeps: timinc

! This is the Marc material routine
!********************************************************************
!
! ************* user subroutine for defining material behavior **************
!
!
! CAUTION : Due to calculation of the Deformation gradients, Stretch Tensors and
! Rotation tensors at previous and current states, the analysis can be
! computationally expensive. Please use the user subroutine -> hypela
! if these kinematic quantities are not needed in the constitutive model
!
!
! IMPORTANT NOTES :
!
! (1) F,R,U are only available for continuum and membrane elements (not for
! shells and beams).
!
! (2) For total Lagrangian formulation use the -> 'Elasticity,1' card(=
! total Lagrange with large disp) in the parameter section of input deck.
! For updated Lagrangian formulation use the -> 'Plasticity,3' card(=
! update+finite+large disp+constant d) in the parameter section of
! input deck.
!
! The following operation obtains U (stretch tensor) at t=n+1 :
!
! call scla(un1,0.d0,itel,itel,1)
! do 3 k=1,3
! do 2 i=1,3
! do 1 j=1,3
! un1(i,j)=un1(i,j)+dsqrt(strechn1(k))*eigvn1(i,k)*eigvn1(j,k)
!1 continue
!2 continue
!3 continue
