(boundary condition file)
(general input file)
These files are used by the program "reform" to construct the main CGWAVE input data
file. Specific steps pertinent to creating each of the above files are provided below.
Open SMS. From the "File" menu choose "import". Select "XYZ data" from the
"Select Import Format" window. Select the drive, directory and file "swanst.xyz" in the
"Open" window. From the tool palette select the "Create Linear Triangle" tool. From the
"Elements" menu select "Triangulate".
Any nodes and elements that lie outside the
desired model domain must be manually removed.
Using the "Select Element" and
"Select Nodes" tools does this. The <Shift> and <Ctrl> keys may be used in combination
with these tools to remove multiple and groups of elements or nodes. For example, a
group of elements may be selected for deletion as follows: Hold the <Ctrl> key, click (do
not release) the mouse button on the center of an element. Drag the pointer across the
group of elements to be deleted. An arrow beginning at the first selection point should
follow the pointer. Any element touched by this arrow will be selected. Elements may be
added to (or removed from) a selection group by holding the <Shift> key while selecting
an element. The selected elements are then deleted with the <Del> key. Other selection
methods are available in the "Edit" and "Elements" menus. Remember to clean up and/or
remove the elements in areas where islands or structures are located. After obtaining a
satisfactory grid-network, boundary conditions must be specified, as detailed in the
Select "Save Geometry" in the "RMA2" menu.
