Package extensions

Extensions load automatically when the corresponding optional dependency is present in the environment:

Extension	Trigger	Provides
`PyrolysisKLUExt`	`using KLU`	`klu_factorization` linear-solver hook
`PyrolysisAMGExt`	`using AlgebraicMultigrid`	`amg_preconditioner`
`PyrolysisPardisoExt`	`using Pardiso`	`pardiso_factorization`
`PyrolysisPlotsExt`	`using RecipesBase` (or `Plots`)	Plot recipes for `PyrolysisSolution`
`PyrolysisSciMLSensitivityExt`	`using SciMLSensitivity, Zygote`	`forward_sensitivity` / `adjoint_sensitivity`
`PyrolysisSymbolicsExt`	`using Symbolics`	`verify_mixing_derivatives` (test-only)

Calling a stub without its trigger dependency loaded raises a MethodError naming the package to load. See the User Guide's extensions section.

Pyrolysis.klu_factorization — Function

klu_factorization()

KLU sparse-direct factorization for the integrator's linear solves, suitable as the linear_solver keyword of solve. The concrete method is attached by the PyrolysisKLUExt extension: load KLU first (using KLU); calling the stub without it raises a MethodError.

Pyrolysis.pardiso_factorization — Function

pardiso_factorization()

MKL Pardiso sparse-direct factorization for the integrator's linear solves, suitable as the linear_solver keyword of solve. The concrete method is attached by the PyrolysisPardisoExt extension: load Pardiso first (using Pardiso); calling the stub without it raises a MethodError.

source

Pyrolysis.amg_preconditioner — Function

amg_preconditioner(A)

Algebraic-multigrid preconditioner built from the sparse matrix A, for use with the ILU/Krylov iterative linear solvers. The concrete method is attached by the PyrolysisAMGExt extension: load AlgebraicMultigrid first (using AlgebraicMultigrid); calling the stub without it raises a MethodError.
