Hi, I am new to Ansys. I want to apply slip flow condition to my pipe. Have any ideas how to do it?
Thanks |

In wall boundary conditions, instead of specifying no slip condition you can do a specified shear condition (where you provide the shear with units of Pa). If you want to do more complicated stuff, it might require a UDF.

how do you calculate the shear stress? Are there any specific equations?
Thanks for replying btw! |

You can get it from Newton's Law if you know the velocity.

Or leave at 0 if you are looking to have a full slip condition
