Unformatted text preview: is never guaranteed. This is one of the problems that we are going to resolve by showing the 3D solution that "best" verifies the specifications. The Ω matrix introduces a maximum of n 2 dependent parameters. If only 3n − 3 k ωi variables are introduced, with a maximum of 3 per vector, we are confronted with an iso-constrained problem, which may or may not have a solution. This traditional approach is unsatisfactory for the designer, who receives a "no solutions" type of message giving him no indication of the nature of the specification changes to be made. This is why we use a different strategy that consists of always providing a real object, as close as possible to the designer's specification, which then clearly indicates the specifications that are not met. For this the problem will always be deliberately underconstrained by systematically introducing more variables than constraints into the Ω matrix. We will solve this undetermination by seeking the G final tensor which minimises the perturbation of the...
