Bürokratieabbau ist kein Problem. Umweltschutzauflagen sind kein Problem - sie lassen sich planen, vorbereiten und sauber in Projekte eintakten.
Politik mit difuser Haltung und Entscheidungsschwächen sind ein schwer planbarer Grund für Projektverzug und eine Herausforderung für #Planungsbeschleunigung
Übrigens nicht nur in Berlin mit der CDU, wie hier von

Abstract: This paper presents experimental validation of the homogenized harmonic balance finite element method (HomHBFEM), which we have developed as a dedicated simulation technique for magnets with fast excitation cycles, in particular the fast corrector (FC) magnets for PETRA IV at DESY. The HomHBFEM allows efficient three-dimensional nonlinear eddy-current simulations of laminated magnets at elevated frequencies with a relatively coarse finite element (FE) mesh and without computationally expensive time-stepping. This is achieved by combining a frequency-domain-based homogenization technique with the harmonic balance FE method. The simulation results for the magnetic flux density along the axis of the FC magnets as a function of frequency and the resulting integrated transfer function (ITF) are compared to Hall probe and search coil measurements of the first prototype FC magnet for PETRA IV. A good agreement between simulated and measured ITFs is achieved for excitation frequencies from 10 Hz to 10 kHz.
