Karsten Wenzke 12 Report post Posted September 3, 2014 (edited) Hey, You want to vary your geometrie and keep the volume or area steady for each design?Then this project file and the presentation is something you should take a look at. With CAESES it is possible to vary your parameterized geometry with a Design Engine and at the same time keep the volume or area at the same value. The presentation guides you through the total setup process.It contains:parameterized geometrycreating parameters for the volumessetting up the internal optimization and the variation algorithmhow to create screenshots after all designs have been createdComparing of the designs with the new introduced Design Viewer functionallityHope you like the presentation and the example project.If you have further questions don't hesitate to ask. Hint: It is also possible to calculate a Volume of a solid object. Just create a Parameter and set the value to 'mysolid.getvolume()'. Please notice that this project file is made for the new release 3.1 of CAESES.The internal Optimization also works with earlier Versions of CAESES. Cheers, Karsten You can find a tutorial in CAESES.The tutorials can be found in the documentation browser > tutorial > learn moreInternalOptimization.fdb05_Fulfilling_Geometry_Constraints.pdf Edited March 11, 2015 by Karsten Wenzke attached new tutorial pdf Share this post Link to post Share on other sites

Mr. Carlo Pasquinucci 1 Report post Posted May 20, 2016 Hey, I prepared one similar project, in which a ship is first deformed using the Lackenby deformation and later the draft is changed in order to have the same displacement as the first ship, using a Brent internal optimization.The equality of the two displacement is checked by an equality constraint. If the displacement is not reach, you can avoid the calculation of the external software.
