Hybrid Nitsche method for distributed computing
Tom Gustafsson, Antti Hannukainen, Vili Kohonen +1
We extend a distributed finite element method built upon model order reduction to arbitrary polynomial degree using a hybrid Nitsche scheme. The new method considerably simplifies…
Distributed finite element solution using model order reduction
Tom Gustafsson, Antti Hannukainen, Vili Kohonen
We extend a localized model order reduction method for the distributed finite element solution of elliptic boundary value problems in the cloud. We give a computationally efficient…
A Ritz method for solution of parametric generalized EVPs
Joanna Bisch, Antti Hannukainen
This work deals with approximate solution of generalized eigenvalue problem with coefficient matrix that is an affine function of d-parameters. The coefficient matrix is assumed to…
Solution of parameter-dependent diffusion equation in layered media
Antti Autio, Antti Hannukainen
This work studies the parameter-dependent diffusion equation in a two-dimensional domain consisting of locally mirror symmetric layers. It is assumed that the diffusion coefficient…
