WebJul 7, 2014 · Rep Power: 11. The problem is that the wall shear stress only can be computed on walls. One possible solution is to write an UDF that applies the definition of the wall shear stress, even if your surface is not a wall: You will need the velocity derivatives and the area vector of your surface. From the definition of the viscous stress tensor ... WebFeb 11, 2024 · Rep Power: 5. I think wall shear in fluid domain is due to viscous forces of fluid flowing past inside of wall, and the shear stress in the solid domain is due to the internal forces in the wall due to displacement of the wall due to fluid 'pushing' it.
