Refinement Region - [source code]
Define a custom snappyHexMesh refinement region (a box, solid or surface) — refines the cells inside/near the geometry to the chosen level. Wire Extras into a case component so the region is written every time the case is written; or wire a written Case in and press Apply to edit the dictionaries in place (which a later re-write undoes).
Input
| Name | Nickname | Description | Type |
|---|---|---|---|
| Case | Optional. An already-written case to edit in place — any Eddy3D OpenFOAM case (wind, Outdoor+ microclimate, indoor, CHT) or a loaded study. Leave it empty and wire the Extras output into the case component instead, which is the durable route: a region applied here is erased the next time the case is written. | Generic Data | |
| Geometry | Geo | The region geometry: a Box/closed Brep/Mesh (use mode inside/outside) or an open surface (use mode distance). Written as an STL into the mesh case. | Generic Data |
| Name | Region key (a valid OpenFOAM word, e.g. "towerWake"). | Text | |
| Level | Lvl | snappyHexMesh refinement level inside/near the region (e.g. 2). Default 2. | Integer |
| Mode | inside (refine the whole closed region), outside (refine everything outside it), or distance (refine within Distance metres of the surface). Default inside. | Text | |
| Distance | Dist | For distance mode: refinement band width in metres. Default 10. | Number |
| Bake | Apply | Write the region STL and snappyHexMeshDict entries into the wired Case's already-written dictionaries (idempotent). Momentary button; re-run meshing afterward to apply the new region. Not needed for the Extras route, which writes the region with the case. | Boolean |
Output
| Name | Nickname | Description | Type |
|---|---|---|---|
| Status | What was written, and where. | Text | |
| Extras | The refinement region as case data. Wire this into a case component's Extras input so it is written into snappyHexMeshDict every time the case is written — including after a re-write, which is what editing the dictionaries in place cannot survive. | Generic Data |
