HI Britt, Do you have list of properties that you would like to see? Cheers Claus
-
You can rename the project, take away the ~ and make sure the project is not opened by another instance of CAESES. Best regards Claus

Please install CAESES after downloading it from our website CAESES.com/downloads Cheers Claus

Same Variants in Genetic Algorithms
Mr. Claus Abt replied to Mr. BUGRA UGUR YAZICI's topic in Ideas and Suggestions
That is actually the case. If you use the result pool, exactly that happens. You can even define an epsilon (at the design variable) which will regard two variable values as "the same" within that range. If e.g. all design variables for a large structure are within 0.1 mm, you should probably not trigger the simulation .... the default is zero. Cheers Claus -
Do you mean the profile shape or the contour?

Multi Segmented Smooth Curve
Mr. Claus Abt replied to Mr. Ashesh Pradhan's topic in General Modeling
HI Matthias, I would probably use a polycurve and assemble it from lines and curves depending on the individual needs of the particular region. Cheers Claus -
HI Rull, First of all you need a software to calculate the resistance (or better the power that is needed to propel your vessel). That could be products by ANSYS, Star-ccm+, FINE/Marine, Shipflow or similar. Then you have to set up a parametric model, or, alternatively import a geometry and apply parametric variations in CAESES. To keep the same displacement, you can either adjust the draught of the vessel to meet the displacement, or you can apply transformation to the vessel that will adjust the displacement at the desired draught in a nested way. Once you have defined the design variables that change the hull form, have connected to the CFD code of choice and calculate the performance, you can use those in a designEngine in CAESES to run automated optimization. You will find some tutorials on each tasks mentioned in the tutorials shipped with CAESES, or in our YouTube channel. Hope that helps to start with, Claus
