ABSTRACT:
Method and apparatus are disclosed for implementing a geometric multi-cell system dynamics model having an embedded grid, the embedded grid having cells with a finer grid size relative to the grid size of other cells. The apparatus includes a digital computer having a computational fluid dynamics model program stored therein, the program having software for iteratively solving transport equations for thermophysical values for the embedded cells and the other cells, and for solving residual equations for the values for each cell using a multi-grid computation method. The program also has other software for computationally manipulating the embedded grid cells to provide composite cells of the same grid size as the other cells and having averaged residual thermophysical values, for allowing the multi-grid computation method to operate on the embedded grid cells.
