It looks like you’re probably calling `include()` on the same file multiple times, which is resulting in multiple different copies of the `VortexElement` module. You essentially never want to include the same file more than once in Julia. Fortunately, this is generally very easy to solve, although I can’t make a precise suggestion without some idea of what your code looks like.
