Hi all, pleasure to join this community !

Bascially i was modelling a steady flow in a blood vessel and was trying to look at some basic parameters like velocity, shear rate, etc. Plotting these gave expected results.

Inlet Velocity was defined as 0.5m/s and outlets were defined as outflow of 0.7 and 0.3 for the main and side outlet respectively.

When i plotted the Wall Shear Variable, the values given to me were in the order of MPa, which should not be the case at all (they are expected to be below 100 Pa in general).

I have attached images of the results below.

Looking forward to your help !
