Basic FDS Example II#

In this example we build on Basic Example I and construct a small room with a fire inside. This setup is based on the “Steckler compartments” [SQR82]. An introduction is also provided in Compartment Fires section.

Note: The individual file paths are likely different on your system, depending on your file structure.
