  • Publication number: 20170017741
    Abstract: A computational engineering modelling tool having a point generation module arranged to read geometry data representing a domain to be modelled. The point generation module also generates point data for the domain having multiple boundary points located on a boundary of the domain and multiple further points spaced from the boundary within the domain. A point mutation module processes the point generation module output and generates automatically a plurality of alternative point data definitions for the domain in which the location of at least one point differs between each of the alternative point definitions. A blocking module discretizes the domain by creating multiple geometric blocks over the domain using a computational geometric operator wherein each point represents a vertex of at least one block. The blocking module outputs a discretized computational model of the domain and the tool scores the model according to a geometric attribute of the blocks.
