JMatPro® MPO v.1.0 released March 2022

We are pleased to introduce a new functionality available for JMatPro® users - the Material Property Optimiser which 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.
