Hello everyone. I want to ask that whether modal DG is implemented in julia or it uses only nodal DG ?

Most solvers use nodal DG. The only exception are `DGMulti` solvers where you can specify the `Polynomial()` approximation type, resulting in modal DG.  
Why do you want to use modal DG instead of a nodal version?
