a20f7062e3 changed: introduce a virtual NonLinSIM::assembleSystem 
allow for overriding how the linear system is assembled.

e3da110cb9 changed: adjust sanity check in ASMxD::updateCoords 
for mixed discretizations there are additional fields present.
to avoid failing in this case, accept any vectors of sufficient size
instead of putting a requirement on the exact length.

use of an additional MADOF is required

32e2418208 Fixed: Removed the 0.5 scaling factor in SAM::normReact. 
Added: Method to check whether we have reaction forces in the model.
Added: SIMbase::getNoConstraints() and SAM::getNoConstraints().
Changed: Removed unused SAM-methods and de-virtualized some others.

c71ced943f Fixed: Wrong input to an evalPoint call when calculating element center. 
Added: Implementation of ASMu2D::constrainNode searching for matching nodes.
This works (although not that efficiently) for interpolatory C0-points,
and is handy for doing adaptive analysis of the single-patch L-shape, etc.

c21ec8a96e Added: virtual method evalSol2 and non-virtual IntegrandBase::evalSol1. 
The latter method can be used when the secondary solution depends on
the first primary solution vector only (which covers most cases).
Then the integrand can override the evalSol2 method instead of evalSol
such that they don't need to deal with the element-level extraction
of solution vectors themselves (the default evalSol will do it).
Also extended the doxy for the initElement and evalSol methods.

Knut Morten Okstad
24ab9e6503 Changed: The enum for system matrix type is now in LinAlgEnums.h 
and we don't need a separate system vector type as
it is directly linked to the specified matrix type.
Added: Option to use UMFPACK in the L2-projection.
 2019-10-25 07:42:39 +02:00

a7b9bd3137 Changed: Put the linear system type flag inside LinSolParams.

fc38e96b3b added: full support for schur-complement block preconditioners 
previously only the SIMPLE (i.e. diagonal of A) approximation was
possible. now, any approximation can be used for A^-1.

4cc284a298 Changed: Use ItgPoint instead of FiniteElement in Field unit tests. 
Moved the ASMSquare and ASMCube definitions to separate header files
to enable reuse in other tests. There was a bug in ASMCube also.
 2019-10-19 11:58:49 +02:00

70176f1408 Added: Class ItgPoint representing an integration/evaluation point, 
the class FiniteElement then inherits ItgPoint.
Changed: All valueFE methods use ItgPoint instead of FiniteElement.

Knut Morten Okstad
61604f40a2 Changed: Dramatically improved the efficiency of the immersed boundary 
calculations when the Alpha function is a spline field, by passing Point
objects also including the spline parameters as argument instead of just
the Cartesian coordinates. Thereby avoiding the costly closestPoint calls.

cd41ae12da Added: Method getCornerPoints returning an array of Point objects 2019-10-16 18:25:20 +02:00

b3cb324f11 Added: class utl::Point as a Vec4 sub-class with internal storage of 
the spline parameters. Otherwise it should work as a Vec4 instance.

bcc7754b36 Changed: Override the getNoNodes method such that it works also 
before the finite element topology is generated for the patch.
Added: Method to print out patch-level element topology.
Added: Virtual method ASMbase::setGeometry.

Knut Morten Okstad
4df9a964c9 Fixed: Invoke initResultPoints() with negative time in project(). 
This is used to signal to the integrand that we are going to
do numerical integration and not just result evaluation.
The initResultPoints call was added in commit 5f5d792 in 2016
to clear the principal stress values buffers, with the side effect
that global L2 projection failed for models with plasticity.
Changed: Made setPatchMaterial const to avoid const_casting elsewhere.
Changed: Minor doxy-issues for extractPatchSolution.

f8d3af7405 added: linear parameter in SIMExplicitRK 
set this to mark operator as linear. this disables
repeated assembly, and reuses factorization if a LU
solver is utilized.

fb4b69dc1e fixed: index check 
we only dereference the second entry, so no reason to require
size to be 3
 2019-08-09 15:13:07 +02:00
Arne Morten Kvarving
48a2f6ad68 added: also store the eigen modes in equation ordering 
so we can output these to hdf5. these are required when doing reduced
order models. this makes it easy to obtain them without having to use
hackery every time.

eab0a41065 fixed: properly setup state in some unit tests 
when we run through the IFEM-test executable, the state
is shared between tests so we have to explicitly set
these values.
