Comparison of two methods for the computation of singular solutions in elliptic problems
Georgiou, Georgios C.; Boudouvis, Andreas G.; Poullikkas, A. (1997)We compare two numerical methods for the solution of elliptic problems with boundary singularities. The first is the integrated singular basis function method (ISBFM), a finite-element method in which the solution is ...

Converged solutions of the Newtonian extrudate-swell problem
Georgiou, Georgios C.; Boudouvis, Andreas G. (1999)Both the axisymmetric and the planar Newtonian extrudate-swell problems are solved using the standard and the singular finite element methods. In the latter method, special elements that incorporate the radial form of the ...

A timestepper approach for the systematic bifurcation and stability analysis of polymer extrusion dynamics
Kavousanakis, M. E.; Russo, L.; Siettos, C. I.; Boudouvis, Andreas G.; Georgiou, Georgios C. (2008)We discuss how matrix-free/timestepper algorithms can efficiently be used with dynamic non-Newtonian fluid mechanics simulators in performing systematic stability/bifurcation analysis. The timestepper approach to bifurcation ...
