1. A method of suggesting a substitute object for a first simulated object for a Computer Aided Design (CAD) tool or in a Computer Aided Engineering (CAE) tool, comprising:

  • improving suggestion of the substitute object for the first simulated object for the CAD tool or the CAE tool by;

    storing, with a processor of a computer system, a plurality of objects on a storage medium, each of the plurality of objects is a part of a model and is associated with a plurality of physical characteristics;

    determining, with the processor of the computer system, a plurality of physical characteristics of the first simulated object, wherein the plurality of physical characteristics of the first simulated object define physical properties of a physical object represented by the first simulated object;

    comparing, with the processor, the plurality of physical characteristics of the first simulated object to the plurality of physical characteristics of the plurality of objects stored on the storage medium;

    based on comparing the plurality of physical characteristics of the first simulated object to the plurality of physical characteristics of the plurality of objects, identifying, with the processor, at least one matching object from the plurality of objects stored on the storage medium;

    comparing, with the processor, at least one physical property of the at least one matching object to at least one user-specified physical property of the first simulated object to identify one or more of the at least one matching object that meet the at least one user-specified physical property;

    generating, with the processor, a list of the one or more of the at least one matching object that meet the at least one user-specified physical property as the substitute object for the first simulated object, wherein generating the list comprises;

    simulating the first simulated object with a plurality of components;

    arranging the plurality of components in a hierarchical graph to form the first simulated object; and

    generating redesign recommendations for one of the plurality of components based on redesign recommendation rules; and

    displaying the list with a user interface.
