Static curves requests

Three types of requests are available for the Static curves window:

  • Step Evolution: results are computed at each step of the specified quasi-static steps range.

  • Snapshot: results are computed for all the abscissa of the object at the specified time step.

  • X-Y Plots: X-Y plots may be drawn for both Step evolution and Snapshot plots types. You must go through the following steps to draw an X-Y plot :

    1. Select the X-Y plot option by ticking the X-Y plot check box

    2. Select X-axis in the Axis selection frame and specify the variable that will correspond to the X-axis (for example X-position along line)

    3. Select Y-axis in the Axis selection frame and specify the variable that will correspond to the Y-axis (for example Y-position along line)

    4. Click the Add curve button to add the X-Y plot into the list of post-processing requests.

Note

In case the Snapshot option is activated, only lines objects are displayed in the Objects box that lists the components of the model.

Features :

  • For a line object, a position must be selected either giving an abscissa or selecting a primary point of the object.

  • For a floater object, one can select either the COG or a fairlead.

  • When stress results are requested, it is possible to specify the number of section points distributed along the steel pipe circumference.

  • When line gap result is requested, it is possible to specify the number of control points on the line. The clearance between two lines is indeed recorded at some control points distributed along the lines which number can be specified. Control points are not necessarily similar to nodes along the lines, which allow for more accurate outputs.

  • Once you have selected all the information needed to define a curve, press the Add curves button.

Tip

When requesting a step evolution, you may specify several abscissa and get all curves shown in the same plot, by using the following syntax:
Abscissa1 ; Abscissa2 ; Abscissa3 ;

When requesting a snapshot, it is possible to specify several time steps and get all curves shown in the same plot, by using the following syntax:
Step1 ; Step2 ; Step3 ;

or

Begin Step End Step

It is also possible to specify series of abscissa with the following syntax :

(S_min>S_max):Delta_S

for example "(0>50):10" would be equivalent to "0;10;20;30;40;50"
