To turn off the stabilising technique used in the solver go to the main file of the viscoelastc model you want and do the etaPEff = 0 in the divTau() funtion or take out the laplacian contributions in that terms that use etaPEff. I think log-conformation formulation do not improve accuracy, but just stabilize for HWNP.
