Input
| Name | Nickname | Description | Type |
|---|---|---|---|
| Case Name | Name | Case name (no spaces). | Text |
| Working Directory | Dir | Working directory (default ~/Eddy3D/Cases). | Text |
| Solids | S | Solid regions (CHT Solid components). | Generic Data |
| Cavities | C | Air cavities (CHT Air Cavity components). | Generic Data |
| Boundaries | B | Face boundary conditions (CHT Boundary components). Unassigned faces are adiabatic. | Generic Data |
| Cell Size | CS | Background cell size (m). | Number |
| Refinement | R | Surface refinement level (each level halves the cell size at region surfaces). | Integer |
| Initial Temperature | T0 | Initial temperature (°C). | Number |
| Duration | D | Transient: simulated seconds — run long enough to reach steady state (the reference wall assembly converged well before 10000 s). Steady State on: the ITERATION budget instead (500 is OpenFOAM's own default for a steady CHT case). | Number |
| Steady State | SS | Solve to steady state instead of marching in time. Right for U-values and thermal bridges, which are defined on the converged field. Duration then counts iterations. | Boolean |
| Extras | Optional user additions from the Refinement Region and Custom Function Object components. Applied every time the case is written. foamMultiRun scopes function objects per region, so set a Region on each one. | Generic Data | |
| Engine | OpenFOAM engine. CHT currently supports Docker/Podman containers only. | Text | |
| Write | W | Click to write the case to disk. Resets automatically so it never re-writes on recompute. | Boolean |
| Clear | X | Click to delete the case folder. Resets automatically so it never re-deletes on recompute. | Boolean |
Output
| Name | Nickname | Description | Type |
|---|---|---|---|
| Case Directory | Dir | Where the case was written. | Text |
| Commands | Cmd | The OpenFOAM commands this case runs, in order. | Text |
| Logs | L | Write log / status. | Text |
| Case | C | The CHT case for the Run component (Containerized engine only for now). | Generic Data |
