This operation significantly reduces the computational cost on the one hand, and on the other hand, it leads to more feasible subspaces. We use a 9095% energy coverage criterion to define the dimension of the subspace. With this criterion, the surrogate-based airfoil optimization in the active ...

Divide \({\Omega _\Theta }\) into a series of subspaces. Calculate the assigned probability of each point with the following formula: $${P_q}=\int\limits_{{{V_q}}} {{P_\Theta }\left( \theta \right)d\theta }$$ (39) \({V_q}\) is the representative volume. The GF bias...
Another main idea of the finite element analysis is that it does not discretize continuous differential operators using finite differences but instead approximates the solution of the equations with functions belonging to finite dimensional subspaces of H1(Ω). Let Vn be a n-dimensional subspace of ...
