Title:
Configuration of a linear solver for linearly implicit time integration and efficient data transfer in parallel thermo-hydraulic computations
Translated title:
Konfiguration eines Lösers für linear-implizite Zeitintegration und effizienter Datentransfer in parallelen thermohydraulischen Berechnungen
Abstract:
An application of linearly implicit methods for time integration of stiff systems of ODEs results in solving sparse systems of linear equations. An optimal selection and configuration of a parallel linear solver can considerably accelerate the time integration process. A comparison of iterative and direct sparse linear solvers has shown that direct ones are the most suitable for this purpose because of their natural robustness to ill-conditioned linear systems that can occur during numerica...     »
