Abstract
A finite volume method for prediction of plastic flows of metal during extrusion processes is described. The method uses discretisation elements of an arbitrary polyhedral shape, colocated variable arrangement, and is based on the SIMPLE algorithm. After discretisation of the governing equations, the resulting system of nonlinear algebraic equations is solved by an iterative procedure, using a segregated algorithm approach. Here it is used for 3D simulation of an extrusion process, showing a very good agreement with experimental and FEM numerical results.
