Numerical modeling of space umbrella-type mesh reflector

“…In this case, the Newton-Raphson method was applied [2]. Nevertheless, a convergence problem for required solution could arise within this method because of unsatisfactory initial estimation [3].…”

“…To calculate the initial reflector equilibrium shape, the nonlinear force density method (FDM) was applied [4] (the first stage of modeling). This method was used in the construction-design of Munich Olympic Stadium [5], the form-finding of space MR cable systems [3], [6] and other structures.…”

“…However, there could be cases of convergence problems in FEM under imposed boundary conditions. In this case, the procedure of sequence node displacement boundary condition changes could be applied [3].…”
