Need a help concerning a pure convection problem

happysmile

Hello all.

I am studying a book entitled 'An Introduction to CFD : FVM approach' by versteeg.

I found two dimensional pure convection problem with discontinuity, and QUICK solver was developed for that problem.

However, my code blowed up in the middle of running. I think source term of the discretized equation is so big which cause the system of the discretized equation to be unstable.

Is there anyone who have an experience to deal with my trouble?

I have a document of the relating equations and numerical descriptions and i can share if leaving e-mail address.

Please reply.

Regards.
