Short Description of Functionality
The program TRASSE is a preprocessor which is used to generate nodal points for the later generation of a finite element grid (dredger grid). A polygon is given to the program by the user. The program generates sufficient additional nodal points to generate a grid at a later stage of the production line. In addition to the polygon data the width of the inner part (width of the fairway), the width of the lateral areas (slopes of the fairway) as well as the inclination of the slopes have to be prescribed. Furthermore the mean distances between nodal points along the fairway as well as orthogonal to it are required.
Input-Files
general input-data (filetype trasse.dat)
Output-Files
- nodal points as structural informations (filetype insel.dat)
- printer file (filetype trasse.sdr)
- (optional) trace of program execution (filetype trasse.trc)
Methodology
Starting with the given polygon parallel straight lines are generated whose direction is coincident with the directions of the different sections of the polygon. If the polygon is not a straight line but has a number of bends the intersections between the straight lines are automatically calculated. The resulting segments are subdivided conforming to the users requirements. In this way all nodal coordinates are generated. The depth of the nodes is calculated from the (orthogonal) distance to the polygon and the inclinations of the inner and lateral areas
