The winnum command sets the number of visualization windows used by MeshTV. Depending on the window manager used, the windows are either automatically placed on the screen for you, or you have to place each window manually. Windows, if they are arranged automatically, are arranged in rows and columns.
When you have multiple visualization windows, the command " winnum 1 " will resize the current active window to be full-screen. The other windows will iconify. The command "winnum 4" will create four windows so that they fit in the visualization window area. If there were already more than 4 windows, the first 4 will resize and the remaining will iconify. If there were less than 4, windows will be added until 4 exist.
The winnum command sets the size of the windows created. New windows are created at the same size as current windows. For example, " winnum 4" produces 4 windows in a 2X2 grid. A subsequent call to winnew would produce a new window which was the same size as windows in a 2X2 grid.
