[deal.II] Neumann boundary condition for the curved domain

2016-12-08 Thread benhour . amirian66
Dear All, I still have problem with implying boundary condition on the curved domain. consider we produce quarter of a ring in 2D with the function "quarter_hyper_shell" and want to impose Neumann boundary condition on the outer surface. In fact we have a force normal to this surface. The other

Hamed, It's difficult to judge these kinds of problems just looking at the graphical output after solving. I would suggest you to look at the constraints in the ConstraintMatrix using ConstraintMatrix::print[1] for a mesh consisting of has few cells as possible. Using DoFTools::map_dofs_to_supp

I just realized that the problem comes from that part of the code that applies relative displacement between bottom and top faces, since there is not corner element distortion when having u_x (0,y)=u_x(L,y)+delta_x and I uncomment the second part of the code namely, { IndexSet

Dear Daniel, I have applied periodic boundary condition on displacement field for a square 2D domain and in order to apply boundary displacement I want to consider relative displacement between pair faces, namely, u_x (0,y)=u_x(L,y)+delta_x and u_y (x,0)=u_y(x,L)+delta_y , using "cons

Hi For 2D (plane strain, plane stress and axisymmetric) and 3D the 1.0/3.0 should be used (not 1/dim). Because for example for a 2D plane stress problem, strain_33 is not zero or for a 2D plane strain problem, stress_33 is not zero. Check the book by Neto and own: computational methods for pl
