Public Functions Documentation

function TransformingSolver

explicit ae108::solve::TransformingSolver::TransformingSolver (
    const cpppetsc::Mesh * mesh
) 

Parameters:

• mesh A valid nonzero pointer to a cpppetsc::Mesh instance.

---

function computeSolution [1/3]

Calls computeSolution with the default assembler calls (ie. calls assembleForceVector or assembleStiffnessMatrix). Passes on the rest of the arguments.

cpppetsc::distributed < cpppetsc::Vector > ae108::solve::TransformingSolver::computeSolution (
    const BoundaryConditionContainer & transform,
    cpppetsc::distributed < cpppetsc::Vector > initialGuess,
    const double time,
    const Assembler *const assembler
) const

Parameters:

• transform The affine transform to apply.
• initialGuess The global (untransformed) vector to start iterating at.
• time This will be used to configure the assembler. @para assembler Valid nonzero pointer.

---

function computeSolution [2/3]

Calls computeSolution wrapping up the local assembler calls into distributed assembler calls. Passes on the rest of the arguments.

cpppetsc::distributed < cpppetsc::Vector > ae108::solve::TransformingSolver::computeSolution (
    const BoundaryConditionContainer & transform,
    cpppetsc::distributed < cpppetsc::Vector > initialGuess,
    const double time,
    LocalForceVectorAssembler assembleForceVector,
    LocalStiffnessMatrixAssembler assembleStiffnessMatrix
) const

Parameters:

• transform The affine transform to apply.
• initialGuess The global (untransformed) vector to start iterating at.
• time This will be used to configure the assembler.
• assembleForceVector A valid callable. It will be called to assemble the local force vector.
• assembleStiffnessMatrix A valid callable. It will be called to assemble the stiffness matrix.

---

function computeSolution [3/3]

The goal of this function is to find the minimizer y of E(P * y + c) -> min, where (P, c) is the provided affine transformation transform . The transform can be used to specify boundary conditions by fixing degrees of freedom in the output of the transform.

cpppetsc::distributed < cpppetsc::Vector > ae108::solve::TransformingSolver::computeSolution (
    const BoundaryConditionContainer & transform,
    cpppetsc::distributed < cpppetsc::Vector > initialGuess,
    const double time,
    const DistributedForceVectorAssembler & assembleForceVector,
    const DistributedStiffnessMatrixAssembler & assembleStiffnessMatrix
) const

More precisely, this function solves the equation E' = 0, which is equivalent to P^t * F(P * y + c) = 0, where F(P * y + c) are the forces at P * y + c.

Parameters:

• transform The affine transform to apply.
• initialGuess The global (untransformed) vector to start iterating at.
• time This will be used to configure the assembler.
• assembleForceVector A valid callable. It will be called to assemble the distributed force vector.
• assembleStiffnessMatrix A valid callable. It will be called to assemble the stiffness matrix.
