1.3. Files for the Sample Diesel Sector Case

The files for this tutorial are obtained by downloading the quick_start_sector_mesh.zip file here .

Unzip quick_start_sector_mesh.zip to your working folder.

  • Sandia_Engine_LTC_EarlyInj.ftsim: This project file is completely configured and set-up, including an Ansys Forte sector mesh, chemistry mechanism, engine specifications, operating conditions, initial and boundary conditions, fuel spray parameters and other simulation settings. The file extension ftsim is for an Ansys Forte simulation case. This project is used in the first exercise in Loading a Preconfigured Project .

  • Sandia.fmsh: An Ansys Forte mesh file for the Sandia engine. The mesh represents a 45-degree sector of the engine cylinder, with periodic boundaries. The format of this type of mesh for Ansys Forte is KIVA-3V-compatible, and such a mesh can be exported as an option from several commercial structured-mesh generators, such as ICEM-CFD and GAMBIT. It can also be created directly within Ansys Forte using the guided Sector Mesh Generator option.

  • InjectionProfile.csv: Data describing the spray injection. The data can be imported from this file through the User Interface or manually entered once you reach the Spray node on the Workflow tree through use of the Profile Editor tool.

  • sandia_bowl_profile.csv: Data describing the piston bowl shape. This profile can be imported or manually entered in the Profile Editor for use by the Sector Mesh Generator to define the bowl shape.

  • UserCrankAngleOutputs.csv: Table of data that contains crank angles going from -22 to +20.

The sample files are provided as a download. You have the opportunity to select the location for the files when you download and unzip the sample files.
