Joachim Berdal Haga successfully defended his PhD
On Thursday 16 June, Joachim Berdal Haga successfully defended his PhD thesis Numerical methods for basin-scale poroelastic modelling. Poroelastic modelling is a method for computing the interaction between fluids and porous structures, for example in sedimentary rock or biological
tissue. Such computations require that large systems of
mathematical equations can be solved. In his thesis, Berdal Haga
explores and develops methods for solving efficiently such systems arising from modelling sedimentary basins.
The thesis consists of a number of scientific works dealing with various aspects of this problem. Properties of the system is investigated under particular conditions, like large jumps in permeability, and methods that can handle such conditions are developed. The methods are developed in such a way that they can be used for solving the problem by supercomputers with thousands of processors.
Prior to the defence, Berdal Haga presented his trial lecture Iterative solvers for large linear systems.
