Precondition STFC

TN-01_PriorityEquationsTestCases

This document discusses the prioritization of equations and test cases within the NEPTUNE Programme’s Preconditioning project, focusing on elliptic and hyperbolic problems.

TN-02_LinearSystemsEquationsPreconditionersRelatingNeptuneProgrammeABrief

This technical report provides a brief overview of preconditioners for linear systems of equations, including their motivation, classes, implementation details, and application cases.

TN-03_ImplicitFactorizationPreconditionersNeptuneProgramme

This report describes the use of BOUT++ and Nektar++ for plasma physics modeling, focusing on the incorporation of preconditioners into these libraries.

TN-04_ImplicitFactorizationPreconditionersNonSymmetricProblems

This report extends the class of constraint preconditioners from symmetric problems to non-symmetric problems. The authors consider the theoretical properties and demonstrate their effectiveness on a set of test problems inspired by the Hasegawa-Wakatani problem.
