Abstract: A method for modeling design of products, the method comprising: a. providing a user with a computer, the computer having software capability locally or remotely accessible to do the following: i. analyze one or more analysis inputs; ii. assemble the inputs for analysis; iii. perform a simulation analysis; iv. generate a report; b. initiating an analysis session on the computer; c. selecting one or more analysis inputs; d. assembling the analysis inputs; e. running an analysis; f. generating a report of the analysis.

Abstract: A virtual model capable of simulating physical deformation of at least a portion of a product to be worn on a body. The portion comprises a thin, flexible material, wherein the model comprises a first zone of compression defining two major surfaces, wherein at least one of said major surfaces further comprises a zone of bending.

Abstract: A computer method for simulating motion of at least a portion of a virtual body is disclosed. The method comprises the steps of: providing a surfaced body model; capturing or computing motion data for an external surface of the surfaced body; dividing the body model into at least two volumes, one of the volumes comprising at least a portion of the external surface of the surfaced body and being a deformable volume, and one of the volumes being a prescribed motion volume, the two volumes defining an interfacial surface; moving the external surface of the surfaced body according to the motion data while computing motion of the interfacial surface; and, simulating motion of the portion of a body by driving motion of the interfacial surface through the computed motion to provide an accurately positioned moving deformable surface that can be used in garment design.

Abstract: A virtual model capable of simulating physical deformation of at least a portion of a product to be worn on a body. The portion comprises a longitudinal fold or pleat and model comprises at least two elements. The two elements are joined along a common boundary of nodes, and the elements offer substantially no bending resistance at the boundary of common nodes.
