Hello,

I am doing a coupled simulation. I modelled three layers. From outside to inside --> human skull (solid); cerebrospinal fluid (fluid); human brain (solid). During the simulation settings for the fluid when you have to create 'Boundary Conditions' for the fluid-solid interface I cannot select 'Total mesh displacement' in the 'boundary details' tab. (see Tutorial 21 Ansys 11, page 361) Does anyone have an idea how this is possible.

Have you activated mesh deformation in the domain settings? Under Mesh Deformation, option should be set to "Regions of Motion Specified", otherwise the mesh deformation options wont show up in the boundary details tab.
