Robust and parallel scalable iterative solutions for large-scale finite cell analyses
John N. Jomo, Frits de Prenter, Mohamed Elhaddad +7
The finite cell method is a highly flexible discretization technique for numerical analysis on domains with complex geometries. By using a non-boundary conforming computational dom…

Parallelization of the multi-level hp-adaptive finite cell method
John N. Jomo, Nils Zander, Mohamed Elhaddad +4
The multi-level hp-refinement scheme is a powerful extension of the finite element method that allows local mesh adaptation without the trouble of constraining hanging nodes. This…

Phase-field modeling of brittle fracture with multi-level hp-FEM and the finite cell method
Sindhu Nagaraja, Mohamed Elhaddad, Marreddy Ambati +3
The difficulties in dealing with discontinuities related to a sharp crack are overcome in the phase-field approach for fracture by modeling the crack as a diffusive object being de…
