Fire Dynamics and Smoke Control Quickly build complex fire simulation models with PyroSim. Import CAD Models PyroSim imports AutoCAD DXF and DWG files. When PyroSim imports a DWG/DXF file, it will treat all 3D face data as obstructions and all other data (lines, curves, etc.) as separate CAD data. The left image of the figure shows the DWG file face data and the right image shows the grid representation that will be used in the FDS analysis. Alternately, a drawing in GIF, JPG, or PNG format can be imported and then used as a background to help you rapidly draw your model directly over the image. Managing Multiple Meshes PyroSim includes tools to help you create and validate multiple meshes. Multiple meshes allow you to: use parallel processing to speed the solution, conform your meshes to the geometry to reduce the number of cells and solution time, and change the resolution of different meshes to focus of regions of interest. Integrated Parallel Processing PyroSim includes support to launch a parallel simulation using MPI. For a single machine with multiple cores or CPUs, parallel processing is an integrated tool and all details are managed for you. All you need to do is define multiple meshes and then select Run FDS Parallel from the solution menu. PyroSim can also be upgraded to run an FDS simulation on a network cluster of multiple computers. Before launching a cluster simulation from within PyroSim, the node installer is installed on each computer that will participate. You will now be able to run the simulation on any number of computers. Run Parallel
