### Backward Euler scheme or Crank-Nicolson method?

Dear Granville,

in order to find a time step suitable for my computations I decided to observe the fastest process appearing in the model I use, namely Alfven waves in plasma physics. The...

I had exactly something like that in mind:) I have been thinking also about the technique of solving the problem linearly but with updating the matrix each n-th step (in order to cut the problem for...

### linear -> quasi-linear -> nonlinear

Hi there:)

I would like to learn what are the possibilities of inclusion of some nonlinear corrections to some pdes being solved with PDE2D. In general the problem I solve is "highly nonlinear"...

Granville,

That's great!:) What is the recipe to estimate the 'IRWK8Z'? How about the second parameter 'IIWK8Z'?

Thanks!

Granville,

That is maybe less promissing than I though - it seems there is always something. Howvere it is good to have such a choice!

Anyway, how about the NOUPDT=.FALSE. option? In few...

### PDE2D for Windows or Linux?

I have some questions concerning the choice of the operating system for efficient PDE2D computations. Presently I am using the Windows.

The problems, which I have been solving for some time use...
