Well-Posedness and Finite Element Approximation of Mixed Dimensional Partial Differential Equations
Fredrik Hellman, Axel Målqvist, Malin Mosquera
We consider a mixed dimensional elliptic partial differential equation posed in a bulk domain with a large number of embedded interfaces. In particular, we study well-posedness of…
Numerical homogenization of spatial network models
Fredrik Edelvik, Morgan Görtz, Fredrik Hellman +2
We present and analyze a methodology for numerical homogenization of spatial networks, modelling e.g. diffusion processes and deformation of mechanical structures. The aim is to co…
Iterative solution of spatial network models by subspace decomposition
Morgan Görtz, Fredrik Hellman, Axel Målqvist
We present and analyze a preconditioned conjugate gradient method (PCG) for solving spatial network problems. Primarily, we consider diffusion and structural mechanics simulations…
