phi2stl v1.0
|
|
Phi2stl is a post-optimization MATLAB program preparing the optimization data for additive manufacturing generating an STL file. It provides a variety of useful tools : scaling, changing resolution, adding thickness to 2D designs, flipping, symmetry, periodicity, and changing orientation. Mainly developed for level-set based optimization methods, the input is expected to be a matrix Φ of a 2D or 3D design, but it can also be used with density-based optimization results. The MATLAB program is available in both GUI and code version |

TOPLSM, a 199-line Matlab program is developed and presented here for the mean compliance optimization of structures in 2D, with the classical level set method. The optimization includes: 1) Upwind scheme for solving the Hamilton-Jacobi PDE; 2) PDE-based Reinitializtion; 3) Calculation of geometric quantities; 4) Finite element analysis in 2D. |
