Boundary constraint

Please login with a confirmed email address before reporting spam

We are trying to solve FSI of a Submerged Floating Tunnel which is fixed at both ends. When i'm modelling with the pipe fixed at the Walls of the fluid domain, its not able to slove that. It always returns a message (Inconsistent Initial Values). Does the module interpret that as discontinous wall condition because that particular surface is being overridden from wall to fixed. When given as a surface constraint, it's not able to solve. When given as a volume or domain constraint it solves but gives back 0 displacement beacuse the body is fixed. But in the actual physical modelthe body is fixed only at the ends. How to overcome this issue?
