Hello,

I have a question for quite a long time. When people simulate viscoelastic flow, they usually do the simulation at Reynolds Number Re=0, in order to simulate the creeping flow. However there is no physical meaning for Re=0, except that the velocity is 0. But when the velocity is 0 then actually there is no 'Flow'.

So why people simulate Re=0?

Why not do the simulation for Re=0.01 or smaller instead of Re=0? Is there great difference between the results of Re=0 and Re=0.01?

Thanks for your reply in advance!
