Does anybody have used the CLAWPACK?

I have a deep interest about wave modeling on a beach, and I tried to get data as using the CLAWPACK. However, the result was NaN numbers. Is there some error of the CLAWPACK or is my process wrong?

Basically, I modified the dambreak application which I download from on the CLAWPACK web site because the Riemann solver of this application was designed to solve the shallow water equation. (applications/shallow/1d/dambreak). As you know, the wave on a beach is shallow water.

I want to see the data which waves on a beach, especially Tsunami condition. (Initial velocity is zero, and I got an initial elevation equation)

So, I changed the qinit.f file;

Xcell=xlower+(i-0.5d0)dx

q(I,1)= -0.017*dexp(-4*(xcell-1.69)**2), q(I,2)=0 because the initial velocity is zero(0) in the Tsunami condition and I got an initial elevation equation.

In addition, I changed the claw1ez.data file; domain of x is 0 to large number for looking wave on a beach.

Is there something wrong in my process or do I need to change other things?

I appreciate on your future help.

HI!

I also am interesting wave modeling. SO, Can I get the CLAWPACK to see? Please let me know.
