Computer-implemented method for setting initial conditions for dynamic simulation of an assembly of objects in a three-dimensional scene of a computer-aided design system

摘要

A computer-implemented method for defining initial conditions for dynamic simulation of an assembly of objects in a three-dimensional scene of a system of computer-aided design, the method comprising the steps of : - providing (S1) the assembly of objects with information relative to kinematic joints linking objects of the assembly ; - providing (S2) a manipulating tool (M) embedded in the scene, comprising a referential with three-axis allowing for each axis a degree of freedom in translation and a degree of freedom in rotation ; - attaching (S3) said manipulating tool (M) to one object of the assembly; - selecting (S4) a degree of freedom of the manipulating tool (M) attached to the object of the assembly ; - inputting (S5) at least one initial condition (IC) according to said selected degree of freedom, an initial condition comprising an initial position and/or an initial speed and/or an initial acceleration; and - calculating (S6) and displaying in real time the dynamic simulation taking into account the initial conditions (IC) previously defined.
