!> @brief Material subroutine for MSC.Marc
|
|
!> @details Usage:
|
|
!> @details - choose material as hypela2
|
|
!> @details - set statevariable 2 to index of homogenization
|
|
!> @details - set statevariable 3 to index of microstructure
|
|
!> @details - make sure the file "material.config" exists in the working directory
|
|
!> @details - make sure the file "numerics.config" exists in the working directory
|
|
!> @details - use nonsymmetric option for solver (e.g. direct profile or multifrontal sparse,
|
|
!> @details the latter seems to be faster!)
|
|
!> @details - in case of ddm (domain decomposition) a SYMMETRIC solver has to be used,
|
|
!> @details i.e uncheck "non-symmetric"
|
|
!> @details Marc subroutines used:
|
|
!> @details - hypela2
|
|
!> @details - plotv
|
|
!> @details - quit
|
|
!> @details Marc common blocks included:
|
|
!> @details - concom: lovl, inc
|
|
!> @details - creeps: timinc
