Hi, I am currently trying to run some simulations using Star-ccm+ for flows inside sub-channels for rod bundles.
I applied fully developed interface on the inlet and outlet in order to get fully-developed solution. There are 4 nodes in the flow direction.
For unknown reason, I get different wall shear stress values on the same circumferential location in the flow direction. I think I should get only one result at one degree if the flow is fully developed. Does anyone know why my result is scattered? Is this right?
Here are some relevant pictures:
