HAM Case - [source code]

Build a heat-and-moisture case for a layered wall. Wire the Case output into the Run component (Containerized engine — hamFoam ships only in the container). Pick a Preset to reproduce one of the two HAMSTAD benchmark tutorials.

Input

Name Nickname Description Type
Case Name Name Case name (no spaces). Text
Working Directory Dir Working directory (default ~/Eddy3D/Cases). Text
Preset P Custom builds the case from the inputs below. The two HAMSTAD entries reproduce the upstream hamFoam tutorials exactly and IGNORE every input below this one. Text
Wall Build-up from the HAM Wall component. Not read under a preset. Generic Data
Outside O Exterior climate (HAM Climate). Not read under a preset. Generic Data
Inside I Interior climate (HAM Climate). Not read under a preset. Generic Data
Initial Temperature T0 Initial wall temperature (°C). Number
Initial RH RH0 Initial relative humidity of the wall (%). Sets the capillary pressure the solver starts from; it derives the moisture content from that through each material's own retention curve. Number
Cell Size CS Target cell size through the wall (m). Cells are additionally clustered toward every layer face. Number
Grading G Expansion ratio clustering cells toward both faces of every layer. Surface moisture fluxes need sub-millimetre first cells; uniform spacing diverges within the first steps. Number
Duration D Simulated duration (days). Number
Write Interval WI Result write interval (hours). Number
Extras Optional user function objects from the Custom Function Object component, applied every time the case is written. A HAM wall has no snappyHexMesh step, so refinement regions do not apply here — the component says so rather than ignoring them silently. Generic Data
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 HAM case for the Run component (Containerized engine only). Generic Data
