redbKIT v2.2

• New prestress solver in FSI module
• POD-DEIM reduced-order models for Computational Solid Mechanics problems
• New problems: FEM_CSM_Spinning, FEM_CerebralAneurysm_C0094, RB_CSMt_Turek, RB_CSM_ShearCube
• Some bugfix
• Resistance conditions for CFD simulations
• SUPG stabilization for ADRt solver (only linear elements are supported)
• Faster CSM assembly routines
• Refactoring of the RB_mixer problem; FOM is now built using redbKIT FEM library rather than being loaded from mat file
• SUPG assembler for steady NS equations
• Automatic installation scripts for MUMPS sparse linear solver

redbKIT v2.1

Changes only affect the FEM_library and the Problems gallery.
In particular:

• new monolithic Fluid-Structure Interaction solver built upon the CFD and CSM solvers
• 3 FSI benchmarks added to the Problems gallery
• added support for flag-specific Dirichlet BC functions in the CFD solver
• minor bug fixes plus some cleaning of the CFD and CSM folders in the FEM_Library

redbKIT v2.0

Major refactoring of the FEM_Library:

• added support for 3D finite elements with unified interface
• new multi-threaded C assembly routines
• new fluid and solid mechanics solvers, both steady and unsteady
• new LinearSolver class with e.g. MUMPS interface
• new abstract Preconditioner class
• interface to Metis for domain decomposition; parallel Additive Schwarz preconditioner available
• interface to FAST package to speed-up matlab built-in sparse command
• harmonic- and solid-extension mesh motion techniques

Implementation and usage example of MDEIM are now available in the RB_Library.

Many new tests and examples in the Problems directory.

Attention: backward compatibility is not guaranteed

redbKIT v1.0

First release of redbKIT. It contains the implementation of the algorithms and solved problems as presented in the companion book:
