• •A Finite Volume solver for a 3D incompressible viscoelastic fluid system is developed.•The divergence free condition is used to derive a pressure equation and a predictor-corrector procedure is applied when solving the velocity field.•Stability analysis and numerical experiments are given to show the robustness and accuracy of our algorithm. In this paper, we develop a Finite Volume solver for a 3D incompressible Oldroyd-B model with infinity relaxation time. The Finite Volume solver is implemented by using a leading open-source computational mechanics software OpenFOAM. We have imposed the divergence free condition as a constraint on the momentum equation to derive a pressure equation and a predictor-corrector procedure is applied when solving the velocity field. Both stability analysis and numerical experiments are given to show the robustness and accuracy of our algorithm. Two concrete examples on a cubical domain and a dumbbell are computed and illustrated.
