In this paper, we present version 2.0 of cashocs. Our software automates the solution PDE constrained optimization problems for shape and optimal control. Since its inception, many new features useful tools have been added to cashocs, making it even more flexible efficient. The most significant additions are a framework space mapping, ability solve topology with level-set approach, support parallelism via MPI, handle additional (state) constraints. update, describe key which is now better-suited solving complex problems.

ABSTRACT The appropriate scaling of deformation fields has a significant impact on the performance shape optimization algorithms. We introduce pointwise gradient constraint to an efficient algorithm for ‐Laplace problems, while complexity remains polynomial. Using this algorithm, we compute descent directions using ‐harmonic approach that fulfill trust‐region type constraint. Numerical experiments show advantages deformations computed with when compared are scaled after computation. This considers, in particular, approximation limit setting and preservation mesh quality during fixed step size.
