Solvers

This library is featuring linear algebra solvers for the solution of spatially and temporally discretized mechanics problems. In its core, it serves as a binding between the LinearAlgebra and the MSolve.Core repos.

Features

• Assemblers: Global matrix assemblers that take under consideration the connectivity of the underlying model supporting various formats including:

  • Dense
  • Compressed sparse row (CSR) (both symmetric and non-symmetric)
  • Skyline

• Ordering: Re-ordering strategies for the full matrices are supported for the minimization of matrix bandwidth

• Direct solvers: Solvers that use factorization are implemented for dense, skyline and sparse formats

• Iterative solvers: Solvers that rely on “guessing” the solution by performing iterations are implemented, including the PCG and GMRES methods

• Domain decomposition solvers: Solvers that rely on the geometric and/or algebraic partitioning of the model at hand are implemented, including:

  • Overlapping methods: The Schwarz method is implemented
  • Dual methods: A series of variants of the FETI method are implemented
