MATLAB codes for efficient 3-D topology optimization Codes use multigrid CG, approximate sensitivity analysis, recycling precoditioners
This repository includes matlab codes that were used in the following papers:
- Amir, O., Aage, N., & Lazarov, B. S. (2014). On multigrid-CG for efficient topology optimization. Structural and Multidisciplinary Optimization, 49(5), 815-829.
- Amir, O. (2015). Revisiting approximate reanalysis in topology optimization: on the advantages of recycled preconditioning in a minimum weight procedure. Structural and Multidisciplinary Optimization, 51(1), 41-57.
The codes are now freely available, please reference the relevant publications in your research work.
Three types of codes:
-
top3d*.m = 3-D minimum compliance topopt using MGCG solver:
a) basic
b) with sensitivity monitoring
-
minV*.m = 2-D minimum volume topopt:
a) basic
b) reanalysis
c) with matrix-free reanalysis
-
minW3d*.m = 3-D minimum volume topopt using MGCG solver:
a) basic
b) matrix-free with recycling preconditioner
c) matrix-free with recycling preconditioner and sensitivity monitoring
Extensions and improvements are strongly encouraged!!!
