Kaskade7 Finite Element Toolbox
Kaskade 7 has been used for generating numerical results in a number of publications, listed below.
Continuous and discontinuous, scalar and vectorial Lagrange and hierarchical elements of arbitrary order on simplices, up to second order on quadrilaterals. First order edge elements, Morley elements.
Adaptive mesh refinement and coarsening with hierarchical, embedded, and residual error estimators.
Multithreaded, NUMA-aware assembly.
Extrapolated linearly implicit Euler, spectral deferred correction methods.
Adaptive time step selection.
Interface to UMFPACK, MUMPS, SuperLU, and Pardiso.
Iterative Krylov solvers, Block-Jacobi, ILU and HB preconditioners, preconditioning by lower order FE. NUMA-aware matrix-vector products.
Geometric multigrid, multiplicative and additive, for P1 and for higher order elements.
Input from Amira and Triangle files.
Output to Amira and VTK files.
