No resistance has been calculated, but unly a few informative plots. In order to get Rt a goal is missed. Define a new global goal F(z) that will return total force exerted by water and air agaisnt the ship motion. The subscript "Z" depends on the reference frame used. In this case ship moves along Z. Knowing that air drag can be neglected when compared with water effect ,the goal value can be taken as total Rt. If only water effect is required, then a Surface Goal must be defined for the external hull surface only. In fact it would have to be done for the submerged hull, but as this is an "unknown" it will depend on water surface shape, taking the whole external surfaces of the hull will return accurately enough results. Wich surfaces to choose will depend on the ship shape and areas distribution. ....... No CFD can think by itself Rt coefficient Cr, can then be obtained by: Cr= Rt/(dens x WA x V²)/2 with Rt = Total resistance force F(z) dens= water density WA = wetted area V = water speed relative to ship. All in consistent units. SI or Imperial. DO NOT USE KNOTS AS SPEED UNITS IN THE ABOVE FORMULA.
Hello, i am making a simple simulation of boat. With the purpose that this simulation can give me best shape of a lower part of a boat in water and that boat has good aerodinamic. So i can make it in real life. Do you have any recomendation about how do i get to this shape without using programming. I am on a schedule, so i would be very happy for answers. Thank you very much!
interesting video! Thank! Is it possible to simulate pitching during simulation? Does the study take into account the possible trim on the bow or stern when placing the load? Those. center of mass displacement
This CFD is not capable of that computation but, trim can be calculated by other means out of solidworks. Then the model can be rotated to fit the new trim and the computation run again. In order to solve for the whole thing as you are asking, a multiphysics solver is required.

What value did you get for the coefficient?
Coba bentuknya di kasih deformasi sama zink anode, flownya bisa lebih akurat bli
wah dikasih nasihat sma orang lapangan, soal nya gue gatau sample kapal yg mna bg yg ada deformasi nya.. haha

hi 10:14 min to insert the load but the file are missing how can be generate it
interesting video!

Hi m Harris, what file did u you used to load the result..i think i m missing something in there at 10:14 ..😭
Hi Zahid, I think u need to load the .fld file in the directory that u used for this simulation.
@@m.harrisnubly506 saya sama nggak jumpa bagaimana caranya
Hai, sepertinya saya stuck di 10:14, bagaimana cara menemukan file .fld nya ya?
Thanks a lot Sir
Cutting plot means?
Excuse me. How can i do animation simulation?
Bang di 10:21 memasukan data 2.fld z data itu data apa ya bang, dapat dari mana bang, mohon di jawab bang🙏 terimakasih
Mas... Air gue animasinya gerak atas bawah... Gimana set dia dari depan ke belakang?
It’s literally taken my laptop 10mins to run the simulation smh
Hello I am using solidworks 2016 and there is no tab for free surface simulation can you please help me. Thanks
Hello Dhanuka dalpadadu, the free surface feature only available on Solidworks 2018 version or higher.
what up
