I’m trying to solve an elliptic differential equation that has multiple derivative terms and wanted to use DiffEqOperators.jl to build the matrices. Is it possible to sum DiffEqOperators and then solve using backslash? When I try this, I get an error. Here’s an example, based on https://discourse.ju…
