Remember me on this computer. What parameter determines the relationship between two spatial solutions at different times? The spatial discretization should be second order for a second order scheme. The next step is to replace the continuous derivatives of eq. Investigate which parameters affect stability, and find out what ratio of these parameters delimits this scheme's stability region.

Both n and i are integers; n varies from 1 to n t total number of time steps and i varies from 1 to n x total number of grid points in x-direction.PDF | On Jan 1, , Pramod Kumar Pandey published A Finite Difference Method for Numerical Solution of Goursat Problem of Partial Differential Equation | Find, read and cite all the research you.

I apologise, but, in my opinion, you are mistaken. Let's discuss it. Write to me in PM.

It is a pity, that now I can not express - it is compelled to leave. But I will return - I will necessarily write that I think.
