Add-on
The JMatPro® Material Property Optimiser (MPO) is a powerful optimisation tool for the design of multi-component alloys. It builds upon the calculation engine behind JMatPro® by combining it with a multi-objective optimisation method. It allows you to perform calculations aimed at identifying optimal values of decision variables that lead to desired material properties.
