Tochnog

Tochnog is a finite element analysis program. It provides parallel and distributed solvers, 2D beams and trusses.
The department of foundation engineering and tunneling of Ed. Zueblin A.G., Germany, sponsors the integration of hypoplasticity in Tochnog. A state-of-the-art version (automatic time-substepping, integranular strains, pressure dependent porosity, cohesion, etc.) will become available later this year. This extends the library of granular material models already present (like the classical elasto-plastic models such as Mohr-Coulomb, Di-Prisco, etc.).
The SuperLU library can be used for equations solving. The sequential library (SuperLU), the multithreaded library (SuperLU_MT), and the distributed library (SuperLU_DIST) all have become available. This supplies a set of fast direct equation solvers (LU-decomposition based) for single processor systems, multiprocessor systems and clusters of workstations.
