Numerical procedure for fluid-structure interaction with structure displacements limited by a rigid obstacle

Blog Article

A fixed point algorithmis proposed to solve a fluid-structure interaction problem with the supplementary constraint that the structure displacements are limited by a rigid obstacle.Fictitious domain approach with penalization is used for the fluid equations.The surface forces from the fluid acting on the structure Topicals are computed using the fluid solution in the structure domain.The continuity of the fluid and structure velocities is imposed through the penalization parameter.The constraint of non-penetration of the elastic structure into the rigid obstacle Kratom Gummies is treated weakly.

A convex constrained optimization problem is solved in order to get the structure displacements.Numerical results are presented.
