At the moment, it may happen that Newton's method diverges and produces larger and larger residuals. Users should be able to specify some (relative) divergence tolerance, so that when this...

FEAT: Add support and tests for Python 3.12

3

This PR adds support for Python 3.12 for cashocs. Closes #325

At the moment, most of the default configuration is duplicated in the demo configurations. This should be changed, so that only the non-default options (so the ones that do alter...

Update the AlgoCG parameter of the configuration

1

At the moment, the parameters for the nonlinear CG methods are specified, e.g., as ``` cg_periodic_restart = True cg_periodic_its = 5 cg_relative_restart = False cg_restart_tol = 0.5 ``` So boolean...

In the config file, users should be able to specify `deformable_subdomains`, which would be a list of integers, indicating which subdomains of a given mesh are deformable. Additionally (or alternatively),...

To incorporate volume constraints in topology optimization, the level-set can be projected (shifted by a constant) to achieve the desired volume. It would be nice to implement this in cashocs,...

Global deformation for space mapping

2

The newly introduced global deformation (see #222) should be used for space mapping for shape optimization (this makes the space mapping also work with remeshing).

Pseudo-transient continuation solver for globalizing Newton's method

1

Pseudo-Transient Continuation seems to be a robust way of globalizing Newton's method. It should be possible to implement this for general problems in cashocs. One note: Users should have the...

Make angle-weighted interpolation for topology optimization available for parallel computing

1

At the moment, topology optimization does not work in parallel.

Cashocs should be able to make more use of logging - particularly with the debug logger (which isn't enabled by default). Things such as the stepsize computation should be verbose...
