A method, apparatus and computer readable medium for performing a computer simulation to predict the behavior or response of a physical object includes receiving at least one selection made by a user with respect to a context of the computer simulation to be performed. Based on the at least one selection, a list of tools, objects and properties is filtered to be displayed to the user with respect to the computer simulation to be performed, to display only those tools, object and properties that are pertinent to the context of the computer simulation to be performed. The filtered listed of tools, objects and properties with respect to the computer simulation is displayed, to obtain user input of which of the tools, objects and properties are to be utilized in the computer simulation.

Context sensitive simulation environment

A method of creating a CAD model from a finite element model includes identifying and characterizing features of interest from the finite element model. Multiple intermediate data structures of the finite element model are created by dividing the input mesh of the finite element model into mesh regions. Feature recognition is performed on each intermediate data structure to identify finite element model features. Features and feature properties are extracted from the finite element model, and a CAD model is created using the extracted features and feature properties.
