Grid deformation for fluid-structure interation

javier

Hello:

I'm trying to separte a region of my control volume to deformate it as the struct (a sail) deform and then merge it in the old mesh to calculate another iteration of the fluid-struct interaction.

But i have the problem of how can i extract this volume respecting the numeration of the nodes and elements, this is important to reassemble the new deformed mesh volume (the boundary conditions to the elastic problem is no desplacemt for the boundaries to keep the new volume with the old form) in the control volume to a new fluent calculation.

Thank´s for all.
