I am having trouble specifying a Dirichlet boundary condition when I attempt to solve the following problem using a discontinuous Galerkin approach adapted from ( link ): \frac{\partial u}{\partial t} + c\frac{\partial u}{\partial x} - a\frac{\partial^2u}{\partial x^2} = 0 on a 1D interval mesh from…

Dirichlet Boundary Conditions for Discontinuous Galerkin (DG) Methods

For a DG problem you should seek to impose Dirichlet boundaries weakly. Not by modification of the underlying linear system by DirichletBCs

I don't see the boundary conditions in time
