Input and output data are accessible using the data tree of the navigation bar on the left. The computational domain with its finite element discretization, various domain properties, initial and boundary conditions, and results are displayed in one or multiple view windows in the middle. Various tools for manipulating data in the view window are available on the edit bar on the right. The tabs in the view window allow fast access to different type of data.
