comment Continuous superposition of bump functions
I forgot to add that with the pcw/s function you have recommended, I will have only one "bump". I am looking at getting a central bump and "satellite" bumps of smaller amplitude around it. I believe these are called compactons.

comment Continuous superposition of bump functions
@HenningMakhold Yes I thought about a piecewise function but decided against it in case in is not "discretized" correctly with finite difference schemes and such. The pcw/s function, however, needs to be three part and I tried that (will include code soon) with no success!

comment Continuous superposition of bump functions
@HenningMalkholm That was a good idea and I tried it. It would seem that the coefficient a would need to be a "curvature" type term? Right now I have discontinuities in my plot. See updated question. Thank you for your input!

@fgp yes. Thank you for catching that. Working on translation as suggested by Henning Makholm below.

comment Continuous superposition of bump functions
@fgp apologies. On a semi regular basis, the engineer in me murderizes the mathematician. The x varies from 0 to L. I hope that provides clarity?

@Dean Here is something that I found extremely useful for Fourier transforms. Link

comment Solve autonomous ODE with Mathematica
Do you have boundary conditions by any chance that you could use to plot the solution? {{w[x] -> -2 (-1 + Tanh[1/2 (-2 x - Sqrt[2] C[1])]^2)}} is what I got on Mathematica as well. What were you expecting?
