Fig. 8From: Error estimation and adaptivity for PGD based on complementary solutions applied to a simple 1D problemComparison between the uniform mesh refinement and the adaptivity method for the integral of the energy of the error as a function of the combination of polynomial degrees. The detail numbers are the the degrees of the approximation in each parameter, respectively \(k_1\), \(k_2\), \(\beta _1\), \(\gamma _1\), \(b_1\), \(b_2\)Back to article page
