A control volume finite element numerical solution of creep problems

This paper presents the novel application of a vertex-centred control volume numerical scheme commonly known as the control volume Þnite element method to creep problems. The discretization procedure is described in detail and is valid for both structured and unstructured grids without alteration to the formulation. This enables complex geometries to be modelled which overcomes one of the perceived drawbacks of the control volume solution techniques. The example chosen to illustrate the control volume Þnite element method concerns modelling the mechano-sorptive creep which occurs during the drying of timber. The numerical results are benchmarked against previously published numerical results and a Þnite element solution
