CFD is based on governing equations, which are generally continuity equation, momentum equations, and/maybe energy equation (consider all of them together as Navier-Stokes equations). All these 3 equations (let's consider the 3 momentum equations as one), after discretizing gives a system of linear equations. My question is, are there separate matrices created for each of these equations or is there just one, sort-of a global matrix created using info from all three questions?
(I am a beginner and am learning discretizing and solution of single PDEs like heat equation but have not studied coupled PDEs like NS equation) Last edited by granzer; September 3, 2019 at 00:41. |

The system is not linear even after the discretization, you have to see as a single matrix. For example, see here http://www.academia.edu/download/431...20-14mrxrh.pdf |
