Figure 1From: A POD-based reduced-order TSCFE extrapolation iterative format for two-dimensional heat equations Classical TSCFE solutions \(\pmb{u_{d}^{n}}\) and the reduced-order TSCFE solution \(\pmb{u_{d}^{n}}\) . The top chart is the reduced-order TSCFE solution \(u_{d}^{n}\) when \(d=6\) at \(n=1\text{,}000\) (\(t=10\)). The bottom chart is the classical TSCFE solution \(u_{h}^{n}\) at \(n=1\text{,}000\) (\(t=10\)).Back to article page
