Web22 There are two general approaches to representing solutions in the discontinuous galerkin method: nodal and modal. Modal: Solutions are represented by sums of modal coefficients multiplied by a set of polynomials, e.g. $u (x,t) = \sum_ {i=1}^N u_i (t) \phi_i (x)$ where $\phi_i$ is usually orthogonal polynomials, e.g. Legendre.
