Hi guys, I am new on this topic and have problems on setting the B.C. on the SWE ( shallow water eq ).When I run my code it goes well but after some step my water heights goes higher and higher ( it behaves still like a cosine function but with a high amplitude ).Thanks

Maybe you've forgotton to divide by 2 some central difference or a middle value .

It's better to let readers know what kind numerical scheme you use for solving SWE? And what do you mean 'higher and higher of h'? After a long long time, h will be still increasing to an unreasonalbe value?

collacation methods with r^3 rbf ( radial basis function ) .My problem is my h value is incresaing instead of having a nice sinusoidal shape( h value at the beginning )

Hi
Now I am using OF-ext-1.6 do some work, I want to use RBFInterpolation. But I don't know how to used the RBF, and there are no such example about RBF. I will be appreciated if someone can give me a example about RBF.
