The following sources have a dependency on _an external material library_ that should be removed to allow one-way coupling: - [ ] [src/FV/src/material/class_material_procedures.f90](../tree/master/src/FV/src/material/class_material_procedures.f90) - [ ] [src/FV/src/material/class_material.f90](../tree/master/src/FV/src/material/class_material.f90) Procedures or objects should be passed in to the procedures in the MORFEUS FV library through interfaces.
