wallGradU does not work in OF 2.2.2
I run utility wallGradU for cases solving by rhoCentralFoam but it generates the gradient of velocity at the wall of zero. This is wrong answer.
Can someone check this ?
I've taken a look into this and wallGradU works perfectly fine. The detail is that it's configured to only work on walls.
For example, if after the mesh is generated, you run this command:
In addition, when post-processing the case in ParaView, to visualize the "wallGradU" field, make sure you have loaded the patches of type "wall" in the "Mesh parts" section, as shown in the attached image.
Thanks Bruno for your response. That's great.
I also have a problem with snGrad() function that I posted at
I will be appreciated if you can help me to figure out it.
