Postprocessing

Results obtained from the calculation process can be analyzed in the postprocessing mode.

Two windows allow you to manage most of the visualization options:

·        View Results window

·        Select & Display Style window

Select & Display Style window allows the user to select, which elements of the mesh should be post-processed, and how the results will be represented.

View Results window allows the user to choose the result to be presented and the way this result will be displayed

For further information about these windows, please refer to the previous example. You can also find detailed information on postprocessing options in the postprocess section of the on-line help (Help>Help).

Press the Next button to continue to Making Graphs.

Making Graphs

As shown in the previous example, the graphs can be easily drawn using the View graph window. This window allows you to select the variable and line (border) to define the graph. Follow the indications of the previous example to draw the graphs.

 

Once the graphs are done, press the Next button to continue to Reporting.

Reporting

Tdyn includes a tool to comfortably create basic reports of the analysis. The reporting tool can be accessed through the menu option Utilities>Create Report. The Create report window (see Figure 70) creates an HTML file with a name problemname.html in the model directory, where problemname is the name of the model. The report can also be saved in a different directory by using the Export option.

In order to create a basic report, follow these steps:

1.      Insert the title of the report in the Title field (see Figure 70)

2.      Insert a description of the problem in the editor that can be opened by pressing Description button. The description will appear in the report below the title.

3.      Create a new report of the analysis by pressing Create.

4.      Inserts current view of the model at the end of the report by pressing Insert button in the insert current view frame. If necessary, fill the Caption field (see Figure 70). When inserting an image in the report with button Insert, caption is the text that appears just below the image describing it.

5.      Edit a text to be included in the report, by pressing Edit text. Inserts the text at the end of the report by pressing Insert button in the insert text frame.

6.      Repeat steps 4 and 5 as many times as necessary. Note that you can also insert pre-processing images, since Create report window is also available in the pre-processing mode.

Report Example

As an example, we will create a simple report including the graphs we have created previously. To do it, insert the text “Wigley example” in the Title field and press the Create button.

Then insert a global view of the model with the caption text “General view of the model”. If you are still in the graphs viewer, open the View Results window and select one variable of the last time step to visualise. Then select View>Zoom>Frame, rotate the model if necessary and press Insert button in the insert current view frame of the Create report window.

Press the Edit text to open the text editor and insert the text “Some graphs showing the wave elevation profile about the hull and a cut parallel to the centreline are shown.” Then press Insert button in the insert text frame to insert the text.

Now open the View graphs window by selecting Windows>Border graph. Then select Action>Draw graphs and insert the graphs with the caption text “Wave elevation graphs”.

Finally you can view the resulting report by pressing View button (see Figure 71).
