Optimisation Module

CHEMICAL REACTORS: A chemical solution is pumped through a catalytic reactor where a solute species reacts in contact with the catalyst surface. The model aims tomaximize the total reaction rate of the solute for a given total pressure difference across the bed by finding an optimal catalyst distribution. Shown is the catalyst distribution (as the height), direction of flow (streamlines) and concentration distribution (color plot).

No matter the engineering discipline, once you have a model of a product or a process, you want to improve upon it. The Optimization Module can be used throughout the COMSOL Multiphysics product family; it is a general interface for computing optimal solutions to engineering problems. Any model input, be it geometric dimensions, part shapes, material properties, or material distribution, can be treated as a design variable, and any model output can be an objective function.

The Optimization Module computes the analytic sensitivities of the objective function to the design variables and considers any constraints imposed upon the problem. One of its methods uses a gradient-based optimization technique based on the SNOPT code developed by Philip E. Gill of the University of California San Diego, and Walter Murray and Michael A. Saunders of Stanford University.

The Optimization Module can be used to solve shape, size, and topology optimization problems, inverse problems such as parameter estimation, as well as time-dependent sensitivity and optimization. With a very general interface, the capabilities of the Optimization Module can be used in conjunction with any combination of other COMSOL products.
