Hi Samuele, adjointShapeOptimizationFoam performs a "topological" optimization of the flow, i.e. it modifies the porosity of each cell; so at the end of the cycle you will know where you have to modify the geometry wrt the distribution of alpha. Web26 de set. de 2024 · Since dolfin-adjoint is a Python-only library, OpenFOAM ® ’s C++ and shell script functionalities should be made accessible in Python. The interfacing between FEniCS/dolfin-adjoint and OpenFOAM ®, for topology optimization, is performed through a library developed in this work (“FEniCS TopOpt Foam”).
