Hello,when we want to compare different configurations of moorings ,is it possible at ansys aqwa or do we have to make the same procedure every time first at the workbench?I mean do we need to create new files for other mooring configurations?And...which is the difference of making the geometry at designmodeller from making it at spaceclaim?

Hi, you can set up parametric analysis for different configurations of moorings. Click the square box before the configuration parameters you would like to change, there will be a "P" appear in the box, and then in Workbench Project Schematic, you can open the parameter set to do parametric analysis.

DesignModeller and SpaceClaim are two different tools. The ways to use them are different, but the requirements for geometry generated for Aqwa are the same, e.g. surface body without thickness, etc.

Hello again.Thank you for the answer.When i say different configuration,i mean different cases of layouts .For example …case 1:parallel moorings for a structure…case 2:perpendicular moorings for the same structure .Or different number of moorings for the same offshore structure.What parameter should i use in this case? …Is it possible to plot graphs of all(for example 3-4 different cases) cases at one diagramm?

Thank you again!

You need to start a new Aqwa model for each of those mooring configurations. AqwaGS can draw and merge the results of different models in one diagram.

Is it ok to put all the data of fixed points and connection points etc and then save with different name the initial model with different configurations every time?

Thank you a lot again!

Yes, sure, you can do that, and the cable definition won't affect the Hydrodynamic Diffraction analysis, so you can also use only one project, and solve the Hydrodynamic Response analysis with different mooring configuration cases, but each time you finish solving one mooring configuration case, copy the Hydrodynamic Response results in the solver file directory into another folder. Then you can use AqwaGS to plot the different mooring case results and merge them together into one diagram.

I think i understood it,but would it be possible please to show it (how to copy the Hydrodynamic Response results in the solver file directory into another folder).....?

[Yu Bi]

Sorry, I mean to copy the Hydrodynamic Response results from the solver file directory to another folder that you use to save Aqwa result files. The solver file directory path can be found in the Details panel of the "Solution" branch in the Outline tree. Copy all the files in the solver file directory, which contains all the modeling and results information of your current analysis. Once you change the mooring configuration and solve the project again, those files will be replaced.

A ok...Thanks for every answer!!You did it for every question i had.
