Dear All, So far I have had no problems with straight boundaries and Dirichlet conditions. However now I have a curved boundary and I would like to prescribe displacement in the direction normal to the boundary.
In the old brick system there is a calass: getfem::mdbrick_normal_component_Dirichlet which seems to be designed exactly for the above task. I do not see however a similar class in the new brick system. There is a function add_generalized_Dirichlet_condition to set a condition of a form H*u=r but using it for my task would require to precompute the matrix field of boundary normals. There is a function asm_normal_component_dirichlet_constraints but using it gets me out of the getfem::model framework -- I mean I cannot use bricks and have to deal explicitly with he tangent matrix, rhs vector and solving the system of equation. Is the above picture correct or am I missing something? What would be the best approach in such situation ?
