Sohail Reddy 253a5b4b79 Added operator weighted inner product. Moved inner product defintions to solvers.hpp/cpp 2025-10-19 13:37:39 -07:00
Sohail Reddy 1808ca1f3a Added class for user-defined inner products. Updated IterativeSolver to use custom inner products. 2025-10-19 01:14:50 -07:00
Veselin Dobrev 56b1a1715a Use DofToQuad::Abs in a few places. Remove unused methods AddAbsMult*. 
Small doxygen tweaks.

Gabriel Pinochet-Soto 9d84c17e0b Add AbsMult to base class Operator 2025-03-28 22:13:22 -07:00
Veselin Dobrev 0a0117d4bc In SLISolver::Mult, support optimized handling of the case b = 0 by 
providing empty b (i.e. b.Size() == 0) as the input; this is allowed
only in iterative mode where it makes sense for smoothing operations.

In class OperatorChebyshevSmoother, in the constructor using the
power method to estimate the maximal eigenvalue, add an optional
random seed parameter used to initialize the starting random vector.

Fix a warning in mfem::internal::sqrt for dual numbers.

Fix a doxygen warning in the definition of SparseMatrix::handle.

Aaron Fisher e758c37691 Removed nearly all leading underscores for variable names. Every once in a while one of these will confilct with standard libraries in an oddball compiler and it's best to just avoid this problem alltogether. 2021-05-10 16:06:51 -07:00
Veselin Dobrev 8ca6247b3e When FormLinearSystem methods define the true-dof versions of 
X and B, use Vector's MakeRef instead of NewMemoryAndSize in the
case when the FE space prolongation is identity.

In MemoryManager::Insert, when re-inserting the same host pointer
allow the new pointer to have d_mt == MemoryType::DEFAULT in the
debug check.

In GridFunction::{MakeRef,MakeTRef} check for identity prolongation
with the method IsIdentityProlongation.

Veselin Dobrev 86895821b9 Re-worked class PANonlinearFormExtension::Gradient to implement 
an Update method, reuse vectors from PANonlinearFormExtension,
and support FormSystemOperator by implementing GetProlongation.

Fix the size of the NonlinearFormExtension operator -- it is an
L-to-L operator.

In class NonlinearForm, add methods to access the interior and
boundary face integrators.

Small tweaks the methods (Par)NonlinearForm::GetGradient,
ConstrainedOperator::AssembleDiagonal, and
RAPOperator::AssembleDiagonal.

Add more doxygen documentation and other comments.
