A damped Newton algorithm for computing viscoplastic fluid flows
Abstract eng: A new damped Newton algorithm for viscoelastic fluid flows is presented in this paper. This algorithm bases on a projection formulation of the viscoplastic problem and an efficient preconditioned iterative solver for the singular Jacobian. A demonstration is provided by computing a viscoplastic flow in a pipe with a square cross section and performance are compared with the augmented Lagrangian algorithm.
