METHOD AND APPARATUS FOR COMPARING A SIMULATION OF A PHYSICAL OBJECT WITH MEASUREMENT DATA OF THE PHYSICAL OBJECT, AND METHOD AND AN APPARATUS FOR GENERATING A FINITE ELEMENT REPRESENTATION OF MEASUREMENT DATA OF A PHYSICAL OBJECT

摘要

A computer-implemented method for comparing a simulation of a physical object with measurement data of the physical object obtained in an experiment is provided. A finite element representation of a virtual object for interacting with a finite element representation of the physical object in order to restrain an evolution of the finite element representation of the physical object in the simulation is provided for a time step tk of the simulation. The method comprises for one or more subsequent time steps tk+i of the simulation determining, based on the measurement data of the physical object for the time step tk+i, (k+i)-th modification data for nodes of the finite element representation of the virtual object in the time step tk+i-1. The (k+i)-th modification data indicates modifications to data assigned to the nodes of the finite element representation of the virtual object from the time step tk+i-1 to the time step tk+i. Further, the method comprises for the one or more subsequent time steps tk+i of the simulation determining the finite element representation of the physical object for the time step tk+i based on the finite element representation of the physical object for the time step tk+i-1, the finite element representation of the virtual object for the time step tk+i-1 and the (k+i)-th modification data. The method additionally comprises outputting information about the interaction of the finite element representation of the virtual object with the finite element representation of the physical object.
