!* $Id$ !******************************************************************** ! Material subroutine for MSC.Marc ! ! written by P. Eisenlohr, ! F. Roters, ! L. Hantcherli, ! W.A. Counts ! D.D. Tjahjanto ! C. Kords ! ! 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 !******************************************************************** !
