This post shows how to draw a ramp in PyroSim, using triangular slabs to approximate the geometry. Ramps are useful when modeling parking garages or pedestrian walkways.
The geometry of the ramp we will model is shown in Figure 1. It rises from Z=0 to Z=3 m. The basic idea is that we will sketch the geometry using triangular slabs and then we will edit the Z coordinates of the slabs.
The video demonstrates the following steps:
- Import an image for sketching.
- Make a flat model of the geometry using slabs. For the slabs that will represent the ramp, use triangles.
- Edit the Z coordinates of the slabs to approximate the ramp.
The final model will approximate the geometry with slabs, Figure 2.
PyroSim rasterizes the slabs so that they conform to the grid-based geometry used by FDS, Figure 3.
