A monolithic FEM approach for the log-conformation reformulation (LCR) of viscoelastic flow problems

Abstract

In this work, we discuss special numerical techniques for viscoelastic flow problems given in log-conformation reformulation (LCR). In particular, we consider Oldroyd-B and Giesekus-type fluids.

We utilize a fully coupled monolithic finite element approach that treats all the numerical variables simultaneously.
