Version Published Release Notes
2.2.3

The comments inside some functions have been modified.

2.2.2

Formulas for p-Laplace energy and its explicit gradient have been corrected.

Performance of "preprocessingNodalPatches" functions (both 2D and 3D) has been improved.

2.2.1

Newly, the Topology Optimization solver allows to compute several mesh refinement levels and generates a table with energy values and evaluation times.

The Ginzburg-Landau problem and the Topology optimization problem have been added

1.1.1

DOI of the published paper has been added to the description.
The citation has been updated.

1.1.0

The performance of the codes has been improved. Additionally, the contents of individual folders have been slightly restructured for better clarity.
