Udzava method with modified Lagrange function for solution problem about fluid flow in infinite tunnel with friction on boundary
The article is to devoted semicoercive model problem with friction. Nondifferentiable functional unconditional minimization, arising in a model friction problem is reduced to differentiable functional conditional minimization. A dual scheme, based on modified Lagrangian functional, is used for solution obtained.
