New vertical steel storage tanks founded on a shallow foundation of a crushed rock ring are planned at the same location of former storage tanks. The dimensions, loads and foundation of the new tanks are identical to the old tanks which were erected 40 years ago and demolished a few years ago. Despite the fact that the new tanks are identical to...

Stability assessment of existing dikes build on soft soil generates questions on the available stability calculation techniques and material models. Especially peat behaviour is not easily captured by standard design methods. This has led to disapproval, based on calculations, of dikes that have been in operation for several hundreds of years....

We propose to discretize the convective and diffusive operators in the (incom- pressible) Navier-Stokes equations in such a manner that their symmetries are preserved. The resulting spatial discretization inherits all symmetry-related conservation and stability properties from the continuous formulation. In particularly, a symmetry-preserving...

In this work, we present a robust and efficient multigrid solver for a reformulated version of the system of poroelasticity equations. The reformulation enables us to treat the system in a decoupled fashion. It is sufficient to choose a highly efficient multigrid method for a scalar Poisson type equation for the overall solution of this...

An aeroelastic modelling of an axisymmetrical airship is discussed in this paper. The main difficulty is due to the fact that instabilities are not axisymmetrical. Furthermore an Euler-Lagrange kinematical coupling is necessary in order to represent the fluid-structure interaction. Our strategy is based on some arbitrary change of domain (for...
