Hi everyone
In several articles I heard about wall shear stress(WSS), but in comsol i don't know if it's possible to calculat. So what's the term used to mesure or calculate WSS in comsol? and if there are some exemples ( cylinders, web tubes)
thanks

Shear stress = shear rate*solution viscosity. If you are using Laminar Flow physics (spf), shear stress = spf.sr*spf.mu where spf.sr is the shear rate and spf.mu solution viscosity. Of course you can give the viscosity as your own parameter.

hi
thanks for the answer, but what's the difference between Wall Shear Stress and the Total Stress
thank againe
best regards
