Mr. rickor orton 0 Report post Posted May 8, 2019 Dear all, I have a hull design that depends on several parameters. In a first run I used an EnsembleInvestigation to find feasable designs whereby I did some parameter optimization.Now I would like to use the feasable designs as input parameters combinations for a SHIPFLOW analysis. Of course this could be all done in one step, but I would like to be able to add some designs manually in an Excelsheet to compare my intuition with hard mathematics. Furthermore, I would like to accumulate the results from several SHIPFLOW calculations per design (basically looking at different Froude numbers) to calculate a parameter to rank the designs based on these several SHIPFLOW calculations. Manual evaluation is out, because we are talking about several thousand results. Obviously I would like to name the designs in a way that I can easily trace them back to my input parameter sets. I already wrote a nice feature to import an arbitrary CSV file into a table to get my desired parameter combinations into SHIPFLOW.Now I see two principle ways to solve that:I could try to create an EnsembleInvestigation in which I try to manipulate the hull parameters before I start SHIPFLOW and after it finishes. I tried that, but ran into some problems (furthermore this is not my preferred way)I could create a feature that sets my hull parameters, creates a copy of the design and runs SHIPFLOW in this newly created design (this approach looks preferable to me since better control is possible).I am experiencing some difficulties with approach 2 as well: I cannot create a copy of the baseline within the feature that apperears properly in the Optimization tab. If I do a copy from the console using design(getcurrentdesign()) I only get an empty new design. How can I create a complete copy within a feature that properly appears in the Optimization tab? How do I change the current design? Can I start an EnsembleInvestigation in such a new design from within my feature? Share this post Link to post Share on other sites
Mr. Claus Abt 14 Report post Posted May 8, 2019 Hi Rickor,You can use the design assembler for running designs of your choice from a spreadsheet, see attachment. For naming of designs there is an option in the general section of the design engines, see pictures below. And for running a set of Froude numbers you can simply set up a number of computations.Hope that helps. CheersClaus Share this post Link to post Share on other sites
