efa6c99665 added: support for dune-istl linear solvers 2016-09-02 09:30:53 +02:00

0364126769 PETSc reboot 
- assembles into a SparseMatrix object
- copies into a petsc system matrix
- domain decomposition handled through the DomainDecomposition helper class
- linear solver parameter class split in a generic setting class and a
  petsc-specific class

f7694c942f changed: do not build dummy petsc code if petsc is not enabled 2016-09-02 09:30:53 +02:00

fbb6185d82 Added: Another preAssemble function in SparseMatrix. 
This locks the sparsity pattern of the matrix.
Will be used in the upcoming petsc / istl updates.

Changed: Make the AIJ members protected.

cad3a7929f Added: A dedicated domain-decomposition helper class. 
This administers the parallel finite element model.
- establishes global node numbers
- establishes global equation numbers
- establishes global DOF numbers
- generates subdomains for schwarz preconditioners
  (if using multiple subdomains for each patch)

78d7f3d818 added: keep track of the type of a Lagrangian multiplier 
'L' for local multipliers (local to a patch/process),
'G' for global multipliers (global system multipliers).

e984835bd7 changed: use HAVE_MPI preprocessor symbol instead of PARALLEL_PETSC 
MPI support will not be linked to PETSc in the future.

1b5330791c Fixed: Allow using the <refine> and <raiseorder> keywords in parallel. 
Translates to local patch index and ignores patch entries on other processes.
The nGlPatches member of SIMbase is now default equal to myModel.size() for
serial runs, such that we don't need to check that it is non-zero all the time
(except for in getLocalPatchIndex, which may be called before it is set).
The latter is now treated as an error conditions and indicates missing
partitioning information for parallel runs.

4fa03d28ab Added: Optionally let SIMbase::getPatch accept global patch index as argument. 2016-09-02 09:12:02 +02:00

bfa72d45fb Added: A SLU optimize function which directly uses the dofc array from SAM.

on meshes with different refinement in the u, v and w directions.

d8be7cae12 Fixed: Don't update iField in the project method in case of multi-patch models 
(gave crash during initial condition generation).

Changed: Using if-then-else instead of switch that gcc 6.0 did not like,
and adding nodal coordinates in the optional array in the same loop.

aa06426e23 added: add IFEM-Darcy to downstream list for jenkins 2016-08-18 12:55:06 +02:00

47f8caa5d8 changed: add basis support to getBoundaryNodes. 
this is needed for mixed domain decomposition establishment.
also rewrite ASMs2D::getBoundaryNodes to something where we can
rely on the ordering of nodes. this is needed for domain decomposition
establishment.

048ed57a03 Added: Additional convergence check in SIMCoupledSI, 
with possibility for application-specific convergence criteria.
Changed: The order of the SIM::ConvStatus enum values reflects severity,
such that may do (stat <= SIM::DIVERGED) to catch both DIVERGED and FAILURE.
 2016-08-05 15:24:25 +02:00
Knut Morten Okstad
4216595c7b Added: Support for absolute convergence tolerance and also the maxIncr 
parameter in NewmarkSIM, with similar interpretations as in NonlinSIM.
The relative tolerance might be problematic if used on stationary problems.

c536ff1610 Fixed: NavierStokes did not build because of missing includes in AppCommon.h. 
Resolve this by moving the parse implementation to a C-file (not a template).
Also added a default constructor initialising the dim member.
Removed obsolete file ResidualOperators.C

49ad398750 Fixed: setMode(DYNAMIC --> STATIC) in NonLinSIM::solveIteration. 
Probably a copy-paste error. At least, with this change
SIMCoupledSI works also for quasi-static simulations.

ed992a2ca1 added: base class for pre-parsing in applications 
- handles -2D/-3D (can be specified in <geometry> tag)
- handles -LR (can be specified in <patchfile> tag)

fce84a436a fixed: don't crash due to no LinSolParams if no info is read from input file 
fix this by always resizing vector to have a single block entry (with
default values).

930a9eaa53 changed: move variable declaration 
to avoid warnings when compiling without hdf5 support
 2016-07-15 14:56:35 +02:00
Arne Morten Kvarving
0f64a9438d changed: hdf5 serial/parallel switch support 
requires a ubuntu 16.04 or equivalent modern distro.

this for a newer cmake, and for the ability to have the serial
and parallel hdf5 libraries coexist on the system.

e47e77e2d7 Fixed: A mis-placed pointer assignment + use memmove instead of memcopy. 
Pointed out by valgrind but did not seem to affect results though.

a4cd4bc42b Added: Another SIMbase::project method for scalar functions and use that in the initial condition handler 2016-07-13 11:42:06 +02:00
Knut Morten Okstad
86aa43566d Changed: Using SplineUtils methods to project functions onto the spline basis 
since it is there anyway, now also accepting time argument.
Changed: Reimplemented ASMbase::addGlobalLagrangeMultipliers using the other
almost similar method, to avoid unneccesary code duplication.
 2016-07-13 11:41:57 +02:00
Knut Morten Okstad
5f90b3140a Fixed: SAM::getNoNodes now should work also when nodeType array is empty, 
and SIMbase::getNoNodes should work for mixed problems when unique=true.

ad1a22c51e Fixed: Adaptive linear elasticity was broken in the attempt to generalize 
AdaptiveSIM to also handle time-dependent problems. This is now reverted
as this class is not well suited for that class of problems.
It was intended for static linear problems only.
