WebI start with a stream function (psi) discretized with CG (continuous Lagrange interpolants) and compute my vector field (u) as: u = curl psi. If u is discretized by Raviart-Thomas … Webwhich has to be appropriately chosen to avoid divergence and sign(˚ 0) is the sign function, which is dependent of the value of the level set function evaluated after the transport of the interface. In practice, sign(˚ 0) has to ensure that the transition between the two species at the interface must be smooth. Therefore, sign(˚
