Hi all,
I wanted to apply Robin boundary conditions, in the nearly-incompressible
hyperelastic model (Mooney Rivlin), using the 3D cylinder mesh. The Robin
boundary condition should be like:
S·n + a·u = 0,
where S is the stress, n is the the normal vector to the surface, u is the
displacement, and a is a parameter representing the elastic response due to
the presence of surrounding tissue (for example 1·10^-2),. Robin BC are
imposed on Gamma_R = Gamma, the surface of the cylinder.
How can I implement this?
Thanks a lot!
