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.

Veselin Dobrev 7a869c30c6 In class TimeDependentOperator, add a new property: evaluation 
mode, see TimeDependentOperator::SetEvalMode() for description.
This new property is now used to support IMEX time integration
in class ARKStepSolver. With this addition the method
TimeDependentOperator::SUNImplicitMult() is no longer needed
and was removed.
