unstructured grid, pure convection, code

harbinyg · May 26, 2010, 06:23

Hi, friends.

Anyone could provide a code for pure convection problem (if the general scalar equation , it is better) on unstructured meshes.

Both FUD and CD as the convection scheme are OK.

I want to have some basic thoughts of how to treat the unstructured grids problem.

Thanks

as for me, I have written the code for multi-dimensional non-orthogonal grids;

now the key problems are two aspects:

1. the grid generation; the triganle mehses are ok for me, but I have not have the gird generator, so I need a data file for grids;

2. how to organize the structured of the code;

they should be some difference when turing from quadrulateral meshes to triangle or hexagonal mesh;

I think the linear system solver is not a problem; but the organize the discretization equation should be

what about your opinion;
