LBM Run Settings - [source code]
Solver controls for the container-based LBM wind engine (grid spacing, warmup and averaging windows, probe layer, GPU, container runtime).
Input
| Name | Nickname | Description | Type |
|---|---|---|---|
| Grid Spacing | dx | Lattice spacing in meters. Cell count grows with 1/dx^3 — halving dx costs 8x memory and ~16x time. | Number |
| Warmup | W | Physical seconds of simulated wind discarded before averaging starts. | Number |
| Averaging | A | Physical seconds of simulated wind averaged into the reported field. | Number |
| Probe Height | Hp | Height above ground of the pedestrian-level result layer (m). | Number |
| Probe Spacing | Sp | Spacing of the result grid (m). | Number |
| GPU | Run the CUDA build of the solver image (needs an NVIDIA GPU + container toolkit; Windows/Linux only — macOS containers have no CUDA). | Boolean | |
| Runtime | Rt | Container runtime. Auto prefers Podman and falls back to Docker; both run the same OCI image. | Text |
| Image | Img | Container image override. Empty = pkastner/openlb-wind:latest. | Text |
Output
| Name | Nickname | Description | Type |
|---|---|---|---|
| Settings | S | LBM run settings for the 'LBM Run' component. | Generic Data |
