Code Validation
Hi, I'm working with a commercial CFD package and I'm looking for basic examples that can be used to validate the code. As I'm trying to model highly convective biological flows with large Peclet numbers, I need to validate the upwinding ability of the software to solve these convective flows. Any comments or advice would be greatly appreciated. Thanks

Re: Code Validation
I think You can do something like this. You can discretize convection diffusion equation and use differenet values of Sc number and you can validate your code against analytical results.

Re: Code Validation
Thanks. As I'm new to CFD, I was wondering if you knew about upwinding. I'm using a finite element code and all the published work refers to the Streamline/Upwind Petrov-Galerkin (SUPG) upwinding technique. However, the upwinding is applied to the Navier-Stokes equations. If I can validate my upwinding against the published Navier-Stokes work, is it possible to assume that the upwing technique is valid for the convection diffusion equation? Again, any advice would be of great help

Hi dev
I was wondering if you knew about upwinding. I'm using a finite element code No I do not know anything about finite elemnt codes and all the published work refers to the Streamline/Upwind Petrov-Galerkin (SUPG) upwinding technique. However, the upwinding is applied to the Navier-Stokes equations. If I can validate my upwinding against the published Navier-Stokes work, Why do not you validate your results ith convection reaction diffusion equation it would not take muc time i guess is it possible to assume that the upwing technique is valid for the convection diffusion equation? Again, any advice would be of great help Pr |
