Webb8 apr. 2024 · In a topology optimization (TO) setting, design-dependent fluidic pressure loads pose several challenges as their direction, magnitude, and location alter with topology evolution. This paper offers a compact 100-line MATLAB code, TOPress, for TO of structures subjected to fluidic pressure loads using the method of moving asymptotes. … Webb11 nov. 2024 · By Fast Radius November 11, 2024. Topology optimization (TO or TopOp) is a mathematical method that optimizes material layout within a given space, taking into account given load or boundary restrictions. Topology optimization allows designers to optimize a mechanical component or part, typically through material reduction.

WebbA 2D topology optimization script was used in order to optimize the stiffness of the two side-girders. The optimized mathematical solutions were then used as an inspiration to develop the 3D shape of the whole bridge. A parametric model was developed to increase the level of flexibility in the pre-design of the 3D geometry.
