"An optimization-based construction procedure for function space based summation-by-parts operators on arbitrary grids"
by Jan Glaubitz, Jan Nordström and Philipp Öffner.
You find the code to produce function space SBP operators via an optimization procedure and to reproduce the results from the paper. The code has several parts. The main parts for testing are:
SchrPics.jl (Test case for the Schrödinger equation)
Convana.jl (For the convergence tests where the operators have to be adapted in bandedpoly.jl)
Bandedpoly.jl (Can be used to construct the operators as well as optest.jl.)
The operator construction is defined in LFSBcon.jl and LFSBcon2.jl.
