System and Method for Determining Fluid Flow of Compressible and Non-Compressible Liquids

摘要

A system and method for determining fluid flow of compressible and non-compressible liquids is described. The system may include input means for receiving a model of an object defined as a plurality of cells having a plurality of nodes P, and a processor coupled to a memory. The processor may be configured for: discretizing a partial differential equation (PDE) corresponding to the received model; for each node P: (i) locating all neighbouring cells that share the node P, each of the neighbouring cells having a cell center; (ii) approximating the PDE at the cell center of the neighbouring cells using the discretized PDE; and (iii) updating a solution of the PDE at the node P by using the approximated discretized PDE at all the neighbouring cell centers; and iteratively updating the solution for all the nodes P from an initial guess until a convergence criterion is satisfied.
