Different boundary shapes with differing potentials

[bokkaebi]

Is it possible to specify the shape of a boundary with a perhaps a function? For example, a sinusoidal boundary that removes particles. Also, is it possible to specify the potential at any given point of that boundary with a function? Thanks

Hi @bokkaebi ,

Yes, you can do everything you describe: https://warpx.readthedocs.io/en/latest/usage/parameters.html#embedded-boundary-conditions

In warpx.eb_implicit_function you specify your sinusoidal embedded boundary profile and in warpx.eb_potential(x,y,z,t) your electric potential.
