abstract = {Using software for large-scale simulations has become an important research
method in many disciplines. With increasingly complex simulations, simulation
software becomes a valuable assest. Yet, the quality of many simulation codes
is worrying. In this paper, we want to collect and structure the challenges for
a systematic simulation software engineering as a reference and the basis for
further research. We describe our own experiences with developing simulation
software and collaborating with non-computer-scientists. We complement our
experienced challenges with a brief literature review. We structured the
challenges for simulation software engineering into six areas: motivation and
recognition; education and training; developer turnover; software length of
life; verification, validation and debugging; and efficiency vs.
maintainability. Overcoming these challenges needs efforts from research
agencies, scientific computing researchers as well as software engineering
researchers.},

abstract = {Finding solutions to higher dimensional problems, such as the simulation of
plasma turbulence in a fusion device as described by the five-dimensional
gyrokinetic equations, is a grand challenge facing current and future high
performance computing (HPC). The sparse grid combination technique is a
promising approach to the solution of these problems on large scale distributed
memory systems. The combination technique numerically decomposes a single large
problem into multiple moderately sized partial problems that can be computed in
parallel, independently and asynchronously of each other. The ability to
efficiently combine the individual partial solutions to a common sparse grid
solution is a key consideration to the overall performance of large scale
computations with the combination technique. This requires a transfer of each
partial solution from the nodal basis representation into the hierarchical
basis representation by hierarchization. In this work we will present a new,
efficient and scalable algorithm for the hierarchization of partial solutions
that are distributed over multiple process groups of an HPC system.},

abstract = {For multi-field simulations involving a larger number of different physical
fields and in cases where the involved fields or simulation codes change due to
new modelling insigts, e.g., flexible and robust partitioned coupling schemes
are an important prerequisite to keep time-to-solution within reasonable
limits. They allow for a fast, almost plug-and-play combination of existing
established codes to the respective multi-field simulation environment. In this
paper, we study a class of coupling approaches that we originally introduced in
order to improve the parallel scalability of partitioned simulations. Due to
the symmetric structure of these coupling methods and the use of 'long' vectors
of coupling data comprising the input and output of all involved codes at a
time, they turn out to be particularly suited also for simulations involving
more than two coupled fields. As standard two-field coupling schemes are not
suited for such cases as shown in our numerical results, this allows the
simulation of a new range of applications in a partitioned way.},

abstract = {The partitioned simulation of fluid{\^a}€“structure interactions offers great
flexibility in terms of exchanging flow and structure solver and using existing
established codes. However, it often suffers from slow convergence and limited
parallel scalability. Quasi-Newton or accelerated fixed-point iterations are a
very efficient way to solve the convergence issue. At the same time, they
stabilize and speed up not only the standard staggered fluid{\^a}€“structure
coupling iterations, but also the variant with simultaneous execution of flow
and structure solver that is fairly inefficient if no acceleration methods for
the underlying fixed-point iteration are used. In this chapter, we present a
review on combinations of iteration patterns (parallel and staggered) and of
quasi-Newton methods and compare their suitability in terms of convergence
speed, robustness, and parallel scalability. Some of these variants use the
so-called manifold mapping that yields an additional speedup by using an
approach that can be interpreted as a generalization of the multi-level idea.},

abstract = {Strongly coupled fluid-structure interaction simulations often suffer from slow
convergence, limited parallel scalability or difficulties in using black-box
solvers. As partitioned simulations still play an important role in cases where
new combinations of models, discretizations and codes have to be tested in an
easy and fast way, we propose a combination of a parallel black-box coupling
with a manifold mapping algorithm as an acceleration method. In this approach,
we combine a com- putationally inexpensive low-fidelity FSI model with a
high-fidelity FSI model to reduce the number of coupling iterations of the high
fidelity FSI model. Information from previous time steps is taken into account
with a secant update step similar to the Broyden update. The used black-box
approach is applied for an incompressible laminar flow over a fixed cylinder
with an attached flexible flap and a wave prop- agation in a three-dimensional
elastic tube problem. A reduction of approximately 55 \% in terms of high
fidelity iterations is achieved compared to the Anderson mix- ing method if the
fluid and the structure solvers are executed in parallel.},

by the high-order discontinuous Galerkin solver Ateles, while we couple the
solvers at the interface by the library preCICE. We discuss a detailed
performance analysis of the coupled simulation on massively parallel systems.
Furthermore, to show the full potential of our approach, we simulate a flow
