TVD schemes for non-uniform grid

S. Malekzadeh · July 15, 2018, 07:13

Hi,
I want to use TVD schemes on the non-uniform grid in a finite volume code and I do not know the formulation of TVD schemes for non-uniform grids.
any body can help me in this matter????

Its the same for uniform grid, you need to make sure that you have to calculate dx and dy for every grid point only once at the starting of the code. Make sure it follows the criteria (sweby)

thanks for your reply,
I do not think so, it should be different from the uniform grid. in the main formulation of TVD, there is nothing to do with dx and dy.

If I am wrong, please help me.
