Viscoelastic fluids are a special class of non-Newtonian fluids. There are several types of viscoelastic fluid models, and
all of them have a complex rheological response in comparison to Newtonian fluids. This response can be viewed as a
combination of viscous and elastic effects and non-linear phenomena. This complex physics makes a numerical simulation
a rather challenging task, even in simple test-cases. Studies presented in this paper are numerical studies of the viscoelastic
fluid flow in several test cases. These studies have been done in OpenFOAM, an open-source CFD package. Implementation
of viscoelastic models and a solver is only available in a community driven version of software (OpenFOAM-ext). One of
the goals of research in this paper was to test the solver and models on some simple test cases. We considered start-up
and pulsating flows of viscoelastic fluid in a channel and a circular pipe. The important thing is that an analytical solution
can be found in these... cases, making in possible to test all aspects of numerical simulation in OpenFOAM. Obtained results
showed an excellent agreement with the analytical solution for both velocity and stress components. These results encouraged
authors’ motivation and a choice to use OpenFOAM for simulation of viscoelastic flows. We hope that our research will make
a contribution to the OpenFOAM community. Our plan for the further research is a simulation of blood flow in arteries with
the viscoelastic solver
