ideal.II: a Galerkin Space-Time Extension to the Finite Element Library deal.II (2408.08840v1)
Published 16 Aug 2024 in math.NA, cs.MS, and cs.NA
Abstract: The C++ library deal.II provides classes and functions to solve stationary problems with finite elements on one- to threedimensional domains. It also supports the typical way to solve time-dependent problems using time-stepping schemes, either with an implementation by hand or through the use of external libraries like SUNDIALS. A different approach is the usage of finite elements in time as well, which results in space-time finite element schemes. The library ideal.II (short for instationary deal.II) aims to extend deal.II to simplify implementations of the second approach.
