Reply To: Reactive ADE for gas flow
Dear Antonio,
I recently had the same problem in my application and we are working on an appropriate implementation of Neumann boundaries for ADlattices. So far I would suggest to transform your flux boundary condition into a dirichlet boundary condition via finite differences. This is for example explained in https://link.springer.com/book/10.1007/978-3-319-44649-3.
Best regards,
Johanna
