Diagrams of result quantities are normally displayed in sections whose density is defined in the Solver setup dialogue. If the need arises the density may be reduced significantly by means of "user-defined" sections. The user may simply define a very limited (or excessive, if s/he likes) set of specific points on the structure (called sections) and the calculated results will be shown in these particular points only.
A section on a 1D member has the following parameters.
|
Name |
Identifies the section. |
|
Position x |
Defines the position of the section on the 1D member. |
|
Coordination definition |
Specifies the coordinate system used for the definition. Either absolute or relative coordinates may be used. The relative coordinate must lie within interval <0; 1>. The absolute coordinate must lie within interval <0; the length of a particular 1D member >. |
|
Origin |
Defines whether the position is measured from the beginning or end of the 1D member. |
|
Repeat |
Specifies the number of section defined at the same time. |
|
Delta x |
If Repeat is greater than 1 (one), this value defines the distance between individual sections on the 1D member. |
Similarly to 1D members, it is possible to define a specific section or section across the slab where the results should be displayed..
|
Name |
Identifies the section. |
|
Draw |
Defines the plane in which the section is drawn. Upright to element = the plane of the result-diagram is perpendicular to the plane of the slab Element plane = the result-diagram is drawn in the plane of the slab X direction = the result-diagram is drawn in the direction of the global X-axis Y direction = the result-diagram is drawn in the direction of the global Y-axis Z direction = the result-diagram is drawn in the direction of the global Z-axis |

Direction of cut |
The section plane is defined by a line (input graphically in the graphical window) and by this "in-plane" vector. See the example below. |
Let us assume a single slab as in the picture.
There are two sections defined. The lines defining the sections are not situated in the plane of the slab but are 1 metre below the slab.
To indicate the vertical direction and help you to understand the picture, four vertical columns supporting the slab are defined. The columns intersect the lines defining the sections: (i) the line defining the left-hand section intersects the two columns on the left and (ii) the line defining the right-hand section intersects the two columns on the right.
The vector defining the left-hand section is set to: 1 / 0 / 1.
The vector defining the right-hand section is set to: 0 / 0 / 1.
It is clearly seen that while the diagram for the right-hand section is drawn directly above the section defining line, the left-hand section is moved to the right in the direction of the X axis. In fact, the diagram is displayed along a line that forms the intersection of the slab and the plane coming out from the section-defining line inclined by 45 degrees from the vertical.
