Hello,

 

Is there a way to extract the data points from a 2d plot, to be used for manual post processing for example? 

 

Best Regards

Rickard Lindstrand

What do you mean by 2d plot? A graphics file format or a table?

Hi Rickard,

 

of course you can export point data with CAESES. With the search function in our forum, you will find that there is already a topic.

Here is the link.

 

Maybe it's necessary that you make some changes in Karsten's feature or you can write a feature by your own for the export. If you have any further question or if you need some help, please ask.

 

Best regards

Patricia

Hello Claus and Patricia,

After running Shipflow I can plot the wave elevation at a certain plain, resulting in a 2d plot. 

computations & results - comp - xpan - free surface - plane cut - 2dplotcurve - 2dplot. It is one of these I would like as a table.

 

Karstens method seem to be for a geometric curve definition.

 

Best regards Rickard Lindstrand

Hey Campus,

 

You are right my export is for CAD objects.

 

The result from the computations (Post-processing) cannot be exported.

You can try to find them in the corresponding file which should be a .cgns file for shipflow as far as I remember.

 

We just extract these values from the cgns files and visualize them.

 

Best Regards,

 

Karsten

For future reference:

 

This feature was actually already included in the Shipflow! 

The commad to enable it is, for example:

 

xpan

     ...

     wavecut( numt = 1, twavec = [-253], dywave = 0.005 )

end

Hey Campus,

if you want, I created a feature in order to go inside the designs and store the parameter values after a run.

 

If you want, you can export or plot the values of the parameters.
