MORFEUS FV Input File

The MORFEUS input file uses the .json input file structure. The input consists of the following sections:

• Geometry
• Materials
• Source
• Boundary Conditions
• Time / Solver Info

Boundary Conditions

There are two types of high-level boundary conditions:

• MATH - These inputs require user-specified math solution BCs
• WALL - These inputs require physics-defined types of BCs

MATH BCs

1. Dirichlet
2. Neumann
3. Robin
4. Dirichlet Map
5. Neumann Map
6. Robin Map
7. Neumann Flux
8. Robin Convection

WALL BCs

Temperature BCs

1. Fixed
2. Adiabatic
3. Flux
4. Convection
5. Convection Map

Concentration BCs

1. Fixed
2. Adiabatic

Velocity BCs

1. No slip
2. Free slip
3. Sliding
4. Moving
5. Free sliding

Position BCs

1. Stationary
2. Moving

Stress BCs

1. Free
2. Prescribed

Pressure BCs

1. Free
2. Prescribed
