Mr. Buddhika Jayarathne 0 Report post Posted February 6, 2014 Hi,I am going to start a research on ship to ship interaction modelling. The cfd modelling part is bit complicated. I want to model two floating ships together in same water with different angles. Pls inform me the possibility of doing it here. Share this post Link to post Share on other sites
Mr. Carsten Fuetterer 9 Report post Posted February 6, 2014 Hi, welcome to this forum. I'm not an expert in the cfd simulation of ships, but I don't see a problem there.I know that the cfd calculation of more ships is possible in Starccm+ and should be also possible in OpenFoam. I don't know about the capabilities of Shipflow. What cfd program do you want to use? The modeling process in FFW of two ships is of course also possible. You can take on ship create an image of it and translate it, or you can create two different ships as well. It is also possible to evaluate the result values of different ships. Sounds like a heavy but interesting cfd calculation and project :-) best regards Carsten Share this post Link to post Share on other sites
Mr. Buddhika Jayarathne 0 Report post Posted February 6, 2014 Hi Carsten, Thanks a lot for the reply. I am planning to use shipflow. Is there any way that I can know wether it is possible in Shipflow, because we need to grab a licence for the project since we do not have one to do trial before hand.

Mr. Carsten Fuetterer 9 Report post Posted February 8, 2014 Hi, I have to ask some of our Shipflow experts, if this is possible, next week. best regards Carsten Share this post Link to post Share on other sites

Mr. Mattia Brenner 6 Report post Posted February 10, 2014 Hi, to my knowledge (and the information I could find in the manual) this is not possible with Shipflow. To really make sure, you should get in contact with the people at Flowtech (the company making Shipflow). The contact address is: info@flowtech.se If you talk about interaction of the two ships, do the have a forward speed? Should the interaction be analyzed in a seaway? Cheers,Mattia Share this post Link to post Share on other sites
Mr. Buddhika Jayarathne 0 Report post Posted February 10, 2014 Hi Mattia, I wrote to shipflow several times asking this and did not get any responce. Anyway I sent an email again with the question. Yes Interaction needs to be analyzed in seaways and one ship may move in a straight path and the other may approach it using different paths and speeds. Any suggestion pls?

Mr. Mattia Brenner 6 Report post Posted February 13, 2014 Ok, if this is related to seakeeping, then Shipflow definitely cannot do it. I think the seakeeping software MAPS, that is developed by Prof. Wei Qiu from the University of Newfoundland, can handle such kind of problems. Other seakeeping codes probably, too, but I am not so familiar with that field. Cheers,Mattia Share this post Link to post Share on other sites
Mr. Buddhika Jayarathne 0 Report post Posted February 13, 2014 Hi Mattia, Thanks for the reply. Actually this not not go in to seakeeping. I think as Carsten said, STARCCM+ or ansys can do this. Thanks again Buddhika Nirman Share this post Link to post Share on other sites
