This is not particularly difficult once you realize that the nonlinear boundary condition simply yields a nonlinear term in the weak formulation. Let's assume that you want to solve the steady state problem, i.e., − k Δ T = f in Ω − k ∂ T ∂ n = F ( T 4 − T ∞ 4) on ∂ Ω. You convert this into the weak form by multiplying the ... WebFor an anti-symmetry condition the reverse conditions apply (displacements in the plane are zero; the rotation normal to the plane is zero). For solid models using solid finite elements, the symmetry or anti-symmetry restraints are restricted to only translational displacements. This is because the solid models are modeled only with either foussard montague
