The implementation is based on the Adaptive-Multilevel BDDC method, while reflecting some recent advancements in the field. Codes are written in Fortran 95 with MPI library. A library is provided, which is supposed to be called from users’ applications. The library provides a simple interface callable from Fortran and C. Some remarkable features of the solver include implementation of the adaptively generated weighted averages on faces on each level, robust face-based selection of corners, arbitrary number of levels of the multilevel method, or continuity of arithmetic averages among subdomains on all faces and edges.
