I am sorry but I really got confused about the words, diffusion, dispersion and dissipation. I have not read the code quite in detail. It just come...

Hi Alberto, Up to now, I have not analysed the numerical diffusion because it is difficult to find out a scheme to compare with. I think an ideal counterpart for comparison should be CDS, with...

I am not quite sure about the reason. One of the explanations can be NVA and TVD has artificial switch which cause non-smooth change of...

Hi there, I was also struggling to find out a scheme for the convection term. But now I think no method will solve all the problems. One solution will be refining your mesh at the location where...

To explain your problem, we need to look at the boundness of the differencing scheme of the convection term. Upwind differencing scheme usually gives bounded results, but introduces a numerical...
