Hi all !

I'm going to write a software that computes the flow of water (rain) down slopes and along rivers. I've got some practical experience with Fluent, and I've read several papers on different solving-methods for incompressible viscous flows, but I miss some basic understanding - how the heck do I get this matrix that is input to the solver ? Is it the coefficients for all equations for all grid nodes put togehter ? Is it possible to compute the equations one by one, that is one grid node at a time ? What would you recommend to read as a 'tutorial' on coding one's own solver ?

Thanks a lot, guys !

E.T.

first you must decied if you need to slove via an itretive method or direct method. you can compute eah coefiicent at at one time. i have developed problem of lmainar mixed convection in the entrance region of circular sector ducts. i used the TDMA method . for resion i put in each set of coefiicents in a single matrix. the norths coeficients they each on matrix and so on .

i if you have any extra help please contact me.
