Hello, I am a student majoring in solid mechanics simulation.
I am currently trying to study fluid dynamics simulation.


I ran the same fluid simulation using fluent and cfx respectively.
The inlet mass flow is 0.0007 kg/s and the outlet static pressure is 90 mmhg.
It's a simple static simulation of a single S-shaped tube.
Both set the fluid as water, which has the same viscosity.

I don't know why the wall shear contours of the two simulations are so different.
thanks for your help.

as the difference about 0.2% check all settings. models you are using, bc, mat properties, so on
