GooseFEM

API additions

• Added "AllocateElemmat".

Other updates

• Updating docs.

API additions

• Added "AllocateQtensor", "AllocateQscalar", "AllocateDofval", "AllocateNodevec", "AllocateElemvec"

API changes

• Removing Paraview interface: replaced by external libraries "XDMFWrite_HighFive" and "XDMFWrite_h5py"

• Element*: "dV" now only returns raw data, the "asTensor" member function (and free function) can be used to convert the 'qscalar' to a 'qtensor'

• Separating sparse solver in separate class to offer more flexibility in the future

• Adding "dot" to "Matrix"

Other updates

• Applying clang-format to source, python API, tests, and examples.

• Adding test GMatElastoPlasticQPot

• Adding test based on hybrid material definitions

• Formatting update: renaming all return variables "out" to "ret"

• Correction zero allocation to allows for dofval.size() > nodevec.size()

• Formatting update xt::amax and xt::sum

• Renaming private function to begin with caps when the function allocates its return data

• Reducing copies when using Eigen

• Reducing default size examples

• Supporting Windows (#87)

• Removing xtensor_fixed

• Using xt::has_shape

• Adding function to compute the edgesize of all elements

• Switching to modern CMake
• Introducing extra build targets
• Starting integrating examples in CI

• Added minimal documentation.
• Completed Python interface.
• Added ParaView/HDF5 support.
• Added Eigen's solver concept.

API changes:

• All member functions that wrap other member functions to allocate data now start with a capital.
• Matrix....solve(...) no longer modifies the right-hand-side. Use Matrix....reaction(...) function to get the right-hand-side that belong to prescribed DOFs (i.e. reaction forces).
• quad.dVtensor is deprecated over quad.DV(rank).

Extensions:

• The headers TyingsPeriodic, VectorPartitionedTyings, and MatrixPartitionedTyings now provide functionality to run periodic simulations.

The code for "Dynamics" has been completely restructured. The implementation now features:

• Immediate decoupling of elements, storing intermediate variables such as the shape function gradients (allowing later re-use).
• Almost everything can now be run in parallel.

First working version, transferred from old modules.
