WebMar 13, 2024 · $\begingroup$ @BCLC Yes, the fact that the map is an immersion implies that the image is a smooth submanifold with boundary, and this is because both domain and target manifold are 1-dimensional. (It would not be always true if only the domain is 1-dim.) So that, as you say, the only extra condition you need is that the image has … WebJul 1, 2011 · A new robust and accurate Cartesian-grid treatment for the immersion of solid bodies within a fluid with general boundary conditions is described.
