As a starting experiment in FEniCS I am trying to solve the 1D wave equation \frac{\partial^2 u}{\partial t^2} = c^2\frac{\partial^2 u}{\partial x^2} with fixed boundary conditions on the unit interval. As initial conditions I choose u_0(x)=x(1-x). For solving the time dependence I want to use the …

Hi wavy, the ArityMismatch arises, since your right hand side L is not a linear form, but a bilinear form. In [1]: len(L2.arguments()) Out[1]: 2 For a linear form the number of arguments should be 1. I didn’t g…

Cool example. I added it to the gallery of vtkplotter.dolfin as an example of 1D visualization (I hope you don’t mind!),
Cheers
