A damped Newton algorithm for computing viscoplastic fluid flows
For the first time, a Newton method is proposed for the unregularized viscoplastic fluid flow problem. It leads to a superlinear convergence for Herschel-Bulkley fluids when 0 < n < 1, where n is the power law index. Performances are enhanced by using the inexact variant of the Newton method and, for solving the Jacobian system, by using an efficient preconditioner based on the regularized prob...
متن کاملA pathsearch damped Newton method for computing general equilibria
Computable general equilibrium models and other types of variational inequalities play a key role in computational economics. This paper describes the design and implementation of a pathsearch-damped Newton method for solving such problems. Our algorithm improves on the typical Newton method (which generates and solves a sequence of LCP's) in both speed and robustness. The underlying complement...
متن کاملTruncated-Newton Training Algorithm for Neurocomputational Viscoplastic Model
We present an estimate approach to compute the viscoplastic behavior of a polymeric composite under different thermomechanical approaches. This investagation incorporates computational neural network as the tool for determining the creep behaviour of the composite. We propose a new second-order learning algorithm for training the multilayer networks. Training in the neural network is generally ...
متن کاملA Numerical Method for the Simulation of Free Surface Flows of Viscoplastic Fluid in 3d
In this paper we study a numerical method for the simulation of free surface flows of viscoplastic (Herschel-Bulkley) fluids. The approach is based on the level set method for capturing the free surface evolution and on locally refined and dynamically adapted octree cartesian staggered grids for the discretization of fluid and level set equations. A regularized model is applied to handle the no...
متن کاملOn the Behavior of Damped Quasi-Newton Methods for Unconstrained Optimization
We consider a family of damped quasi-Newton methods for solving unconstrained optimization problems. This family resembles that of Broyden with line searches, except that the change in gradients is replaced by a certain hybrid vector before updating the current Hessian approximation. This damped technique modifies the Hessian approximations so that they are maintained sufficiently positive defi...
