Techniques include either sobol or generalized for stochastic collocation and either sobol, decay, or generalized for polynomial chaos. Each of these automated refinement approaches makes use of the max_iterations and convergence_tolerance iteration controls. 7 8Topics:: 9Examples:: 10 11Theory:: 12Faq:: 13See_Also:: 14
