Hello, everyone.

With a common mesh continuum, 'free-slip' or 'no-slip' boundary conditions can be chose in the 'Region - Boundaries - Shear Stress Specification' option'.

However, when i tried a 'Parts Meshes', which i created using 'directed mesh' method. the 'Shear Stress Specification' option' disappeared....i cant find it..

Then, how could i set the boundary slip condition??

i used the 'directed mesh' because i wanna created a uniform mesh.

Any ideas??

thanks!!
