I'm getting

Introduce nnodePeriodic for all meshes, sync with Mesh::Quad4::Regular

• Mesh::Quad4::Regular
• Mesh::Quad4::FineLayer
• Mesh::Quad8::Regular
• Mesh::Quad8::FineLayer
• Mesh::Tri3::Regular

Notably all "static" example. Note that it would be good to add non-linear history dependent examples with fixed displacements.

Use the new rank members from xtensor to pave the way for removing the copies in the Python interface

• overdamped/Verlet
• overdamped/velocityVerlet
• eta=00.10__alpha=0.00
• eta=00.10__alpha=0.20
• overdamped

Benefit:

• Keeps examples up-to-date.
• Forces good CMakeLists.txt
• Makes sure that examples stay up-to-date with material model.
• Allows extension to other OS.

Also (temporarily) deprecate all support functions.

E.g.

using T2 = xt::xtensor_fixed<double, xt::xshape<2,2>>;

In ElementQuad4.h

Examples:

• https://github.com/conda-forge/eigen-feedstock
• https://gomss-nowcast.readthedocs.io/en/latest/conda_pkgs.html
• https://gist.github.com/zshaheen/fe76d1507839ed6fbfbccef6b9c13ed9

cd /path/to/GMatElastoPlasticFiniteStrainSimo
cd conda-recipes
conda config --append channels conda-forge
conda build --croot /tmp/cbtmp .

• MatrixDiagonal.h
• Vector.h

Simplify implementation using new T2s::Copy( ... ) with one argument.

This way:

ce[m,i] = Ae[m,i,j,n] * b[n,j]

whereby Ae comes from

np.einsum('mi,ijkl,nl->mjnk', dNdx, A4, dNdx)

Note that the current definition is just

np.einsum('mi,ijkl,nl->mjnk', dNdx, A4, dNdx).reshape(nne*ndim, nne*ndim)

Implement:

• asDense
• asSparse
• set

(and add to python.cpp)

It may be wise to create a more transparent setup.py in which xtensor, xtl, xsimd are automatically downloaded (as is pyxtensor).

Benefit:

• Forces good setup.py
• Allows extension to other OS.

When default arguments were introduced to program gave a segmentation fault.

Increase readability of CMakelists.txt, see https://github.com/tdegeus/ElastoPlasticQPot/blob/master/src/CMakeLists.txt

Rename m_tyings to m_nodaltyings

Apply code style everywhere.
