The performance of chemical processes is often determined by the selectivity and activity of catalysts used in them. Optimizing a catalyst accordingly leads to a high-dimensional constraint optimization task for both continuous and discrete variables. To solve that task, genetic algorithms are most frequently used in catalysis, though their routine use is still hindered by a lack of appropriate...

A finite element based level set method is proposed for structural topology optimization. Because both the level set equation and the reinitialization equation are advection dominated partial differential equations, the standard Galerkin finite element method may produce oscillating results. In this paper, both equations are solved using a streamline diffusion finite element method (SDFEM). The...
