[SasView Users] Core + 2 shells cylinder model

Hello, I'm a PhD student in the chemical engineering dept. at the Technion institute of technology, Israel. I study carbon nanotubes dispersions stabilized with dispersants using SANS. I am looking for a model similar to the idea of "core_multi_shell" but for a cylinder instead of a sphere. I need a cylinder with a core and 2 concentric shells, each shell has its own SLD. Are you familiar with such a model? I've looked in the search engine and in the marketplace but could not find such a model. Best, Irena Levin
