Multilevel BDDC solver library ============================== Install notes: -------------- 1. Create a make.inc within the main directory - can be done by editing make.inc.example make sure all necessary external libraries are available: These include: BLOPEX ( http://code.google.com/p/blopex ) MUMPS ( http://graal.ens-lyon.fr/MUMPS ) ParMETIS ( http://glaros.dtc.umn.edu/gkhome/metis/parmetis/overview ) LAPACK ( http://www.netlib.org/lapack ) BLAS ( http://www.netlib.org/blas ) ( LAPACK and BLAS are often included in numerical libraries such as MKL ) 2. type make This should first compile object and modules of src/ folder, create library libbddcml.a in lib/ folder, and finally compile example solvers in examples/ solver. For additional info, see http://www.math.cas.cz/~sistek/software/bddcml.html In case help is needed, write to Jakub Sistek ( email@example.com ). The library provides a simple interface callable from Fortran and C. The solution proces is operated by several routines consequently called. Two different modes are possible for input - user can either provide information about global mesh and a file with element matrices, or - user can provide division into subdomains on the first level and pass subdomain matrices for each subdomain to the routine
