Abstract:
1. A method for design of experiments using direct surface manipulation of a mesh model, said method comprising the steps of: selecting a geometric model, wherein the model is in a computer-aided design (CAD) format; converting the geometric model into a mesh model; evaluating the mesh model using a computer-aided engineering (CAE) analysis; determining whether to continue generating the design of experiments response; modifying a surface of the mesh model by varying a predetermined parameter, wherein the surface is modified using direct surface manipulation (DSM) by defining a sketch plane containing a domain of a DSM feature, positioning the sketch plane relative to the surface of the model, locating a reference center within the domain, projecting a vertex located on the surface of the mesh model into the domain of the sketch plane, specifying a maximum displacement of the DSM feature by locating a reference vector centered at the reference center to define the height of the DSM feature in object space, specifying a basis function to determine a displacement of the vertex, determining a displacement of the vertex relative to the DSM feature using the basis function, and using the displacement of the vertex to modify the surface of the mesh model, the mesh model is updated and the updated mesh model is used in continuing generating the design of experiments response, if determined to continue generating the design of experiments response; and using the results of the CAE analysis for the design of experiments.
