Mr. Claus Abt

Hi Atiyah, Short question, why would you want to keep the wetted surface area? Best regards Claus

In the hydrostatics calculation you define "sink" which will define the draft you want to calculate. The upper part will then not be considered. Best regards Claus

HI Christina, you can copy the feature definition into your feature directory or define a new location in "custom features, set custom locations". Alternatively you can edit the feature if you double click on the feature or click on the edit-icon next to the name "repair" and then export the feature definition in the "general" tab to any directory that you then include in your custom locations. Best regards Claus SurfaceLoftingSections.fdf

Multibody STL works the best ....

HI Matheus, You should be able to run CAESES 4 also utilizing the float license issued for your team. Then you have to start CAESES (float license) from the start menu. Best regards Claus

Dear Lucie, I guess it is best to ask FlowScience for assistance how to run Flow-3D in batch mode .... Best regards Claus

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

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

Depends a bit on your computer resources. If you can do many evaluations, it is fine. You can also try the Dakota surrogate models to save time and cpu-hours.

Do you mean the profile shape or the contour?

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

Please take a look into the documentationBrowser and watch some video tutorials on our website.

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
