Abstract
Methods, computer program products, and systems can be used to simulate physical processes. One of the methods includes determining an input flux to be applied to a first element. The method includes determining an applied flux, the applied flux being an amount of flux that can be applied to the first element without causing numerical instability. The method includes determining a balance flux, the balance flux being the difference between the input flux and the applied flux. The method also includes providing the balance flux to a second element.
Claims18
A computer-implemented method for simulating a physical process comprising the steps of:
- determining an input flux to be applied to a first element;
- determining an applied flux, the applied flux being an amount of flux that can be applied to the first element without causing numerical instability;
- determining a balance flux, the balance flux being the difference between the input flux and the applied flux;
- and
- providing the balance flux to a second element.
A non-transitory computer readable medium storing instructions that when executed cause a computer processor to perform operations comprising:
- determining an input flux to be applied to a first element;
- determining an applied flux, the applied flux being an amount of flux that can be applied to the first element without causing numerical instability;
- determining a balance flux, the balance flux being the difference between the input flux and the applied flux;
- and
- providing the balance flux to a second element.
A system for simulating a physical process, comprising one or more processing devices and one or more hardware storage devices storing instructions that are operable, when executed by the one or more processing devices, to cause the one or more processing devices to perform operations comprising:
- determining an input flux to be applied to a first element;
- determining an applied flux, the applied flux being an amount of flux that can be applied to the first element without causing numerical instability;
- determining a balance flux, the balance flux being the difference between the input flux and the applied flux;
- and
- providing the balance flux to a second element.
