WebThis document presents a FEniCS tutorial to get new users quickly up and running with solving differential equations. FEniCS can be programmed both in C++ and Python, but this tutorial focuses exclusively on Python program-ming, since this is the simplest approach to exploring FEniCS for beginners and since it actually gives high performance. WebSolve wave equation with central differences. Plot some nice figures. We will be interested in solving heat equation: ut − Δu = f in Ω × (0, T), ∂u ∂n = g on ∂Ω × (0, T), u = u0 on Ω × {0} using θ -scheme discretization in time and arbitrary FE discretization in space with given data f, g, u0 . θ -scheme time-discrete heat ...
