Figure 4From: Numerical methods to simulate moisture dynamics in fibrous sheet Comparisons of the numerical and exact solutions for Test 1. The computational results with (a) \(m = 2\), (b) \(m = 3\), and (c) \(m = 4\). The contour lines for \(u = 0.1n\) where n represent non-negative integers are depicted: black lines are for numerical solution and grey lines for exact solutions.Back to article page
