Mission confiée
Context
This project follows the line of long term reserach on the development of improved discretizations for complex PDEs. Here the main focus are hyperbolic balance laws arising in many applications in physics and engineering. More particularly this project looks at so called structure preserving methods whichembed genuinely discrete analogs of continuous constraints. Examples aresolenoidal constraints and curl involutions, which also include heenhanced preservation of steady states, often referred to as well balanced. Other constraints as non-negativity or bounded variationwithin physically admissible values are also of great importance.
This work follows initial activities on the so called global flux quadrature (GFQ) approach, which has been shown to provide great enhancements in the approximation of stationary states, including multiD solenoidal constraints (see e.g. [The postdoc will contribute to the investigation of several possible extensions of the approach, going from its application to more complex PDE systems, to the methodological enhancements discussed below.
Principales activités
Specifically, we aim in the coming years to develop the following aspects
The relations with other techniques as e.g. dimension by dimension extensions of the correction method using local solutions of 1D Cauchy problem proposed in [CP20] will also be investigated, as well as their coupling with high order embedded boundary techniques, somewhat in the spirit of [C23,S18].
