HOW TO INTEGRATE THE UPPER CONVECTED MAXWELL (UCM) STRESSES NEAR A SINGULARITY (AND MAYBE ELSEWHERE, TOO)
I propose a scheme to integrate the stresses of the upper convected Maxwell (UCM) fluid which avoids the down-stream instability near a reentrant corner. The scheme is based on representing the stress in a natural basis which is aligned with the streamlines.
