METHOD AND SYSTEM FOR REAL-TIME SIMULATIONS USING CONVERGENCE STOPPING CRITERION

Abstract:

System and method is disclosed for a real-time simulation of a physical system using an iterative solver, such as a finite element solver, or other solvers having a mesh size independent stopping criterion. The method includes: calculating a potential solution for a set of equations used to simulate a characteristic for a model modeling a physical system; determining a difference between the potential solution and a previously calculated potential solution; determining if a stop condition is satisfied based on the difference, where the calculation is performed iteratively until the stop condition is satisfied; and generating an output to indicate the potential solution as a steady state solution or a stall solution for the simulated characteristic of the physical system according to the determining if the stop condition is satisfied.
