different order for wall shear stress result in steady & unsteady simulatiom
 

Hello experts.
I'm working on bifurcation artery. I have a series problem with wall shear stress result:

if I do steady simulation or case file relative to unsteady simulation,the order of wall shear countour become 10^6 and this isn't reasonable but I recieve true and reasonable result in dat file of unsteady simulation and in this state the order of wall shear stress become 10^1.

I think my simulation is correct because I did my simulation similar to youtube's videoes but in result, I have a problem with wall shear in steady state( or case file in unsteady state)

I'm disappointed in my wall shear stress results.
please help me.
