Next: 14.2.8 Get_Harmonic_Diffusion_Coef_Ortho_Diffusion Procedure Up: 14.2 Ortho_Diffusion Class Previous: 14.2.6 Evaluate_Gradient_Cells_Ortho_Diffusion Procedure
The Evaluate_Ortho_Diffusion procedure evaluates an Ortho_Diffusion Term, that is, the - 71#31D72#3273#33 term, in its discretized form, at the cell centers.
Calling syntax:
| call Evaluate (Diff_Term, Phi_MV, Div_D_Grad_Phi_Cells) |
Input variables:
| Diff_Term | The Ortho_Diffusion Term to be evaluated. | ||
| Phi_MV | The Phi Mathematic Vector to use in the evaluation. |
Output variables:
| Div_D_Grad_Phi_Cells | The value of minus the divergence of D times the gradient of Phi for each cell. |
The Evaluate_Ortho_Diffusion code listing contains additional documentation.
