Hello,

I am trying to build a viscoelastic flow model in comsol. It's basically incompressible stokes-flow, but not with the standard viscous rheology. Rather I want to use a viscoelastic Maxwell material model instead.

Can I use the laminar flow Physics? In the equation view of the fluid properties I am able to change the terms for stress calculation, but will that work?
How do I make sure the equations have some kind of 'memory'?,For the simple viscous flow this is not necessary, but with viscoelasticity I need that.

Thank you,
Sebastian
