2. MODELING

CHAPTER 2 "MODELLING" 38 The arcs that appear define the local axes of the surface features, according to the clockwise screw rule. The direction of the arc indicates the x and the point at its edge, the direction. In the new version of the program, the local axes in the surface finite elements are now displayed in 3D for a better overview, following the well-known convention of the right-handed screw and in colours: Red axis (Red) : X Green axis (Green): Y Blue axis (Blue): Z Also, the display of local axes for both linear and surface finite elements has been enabled in the Results section. ❖ The field on the right is for defining the main direction of the reinforcement (direction X,Y,Z) for the vertical meshes. - For vertical grids // on the X-axis : I select the grid and from the list and the column ''s'' is updated, respectively, - For vertical grids // on the Z-axis: select the grid and from the list and the column ''s'' is updated, respectively - For meshes that are not // on either X or Z if I do nothing the program will project the resulting armature by reducing it to the 2 main axes. Alternatively I can use the command .
