- In this tutorial we have learnt about the physics of ship hull analysis with multiphase flow. we have also seen that how our 3d problems can be solved with 2d assumptions.
the geometry of ship is given below, IGS format

It's possible to use this settup for roll decayment analysis? If yes then what changes I would need to make? Since there are only Drag, Lift and momentum in the monitours part.
I though of creating a plane in XY e do the same procediment, is that right? After that to monitor the decayment how could I proceed?
Thanks for the video!
Thanks alot!
This video is awesome. could you please make on 3d model and also show all forces acting on sailboat.
I have some doubts please reply for this
1) how to change the wind direction.
2) how to non dimensionalise in between two medians.
3) how much around force values has to be.
I am thinking to make, requires your help is you have some research papers regarding this kindly send at ashrafb536@gmail.com
@@AnsysLearningPoint I don't have have any research papers and also I am searching for those. could you please make 3d model simulation with more details as soon as possible. if you have answers regarding my previous questions please send or add on your next video's.
could you please reply to my question if know answers.
Ok I'll add them in next
While solving for 3d boat hull using symmetry plane, did the forces and drag coefficient are same for full model and symmetry model or multiplied by 2?
It is same for full model when you use symmetry command otherwise it will be halved
I solved by creating half model only
@@pranaymohite9725 ok bro
@@AnsysLearningPoint understood
Thank you
I still didn’t find at what value the solution became successful. Can you provide the values ..?? Thanks in anticipation.
Thanks for messaging! I don't have data in my PC and I have to my new workstation that's why I have lost all my stuff.
can we import the pre ansys fluent study to structural simulation for understanding the hull structure deformation due to wave impact
Yes you can couple the fluent study to ansys structural
@@AnsysLearningPoint Thanks for revert. hey can you please make a tutorial of explosion under ship structure.
Yes if you can send me a research regarding this then I'll
@@AnsysLearningPoint can you please provide me your email.

Hi! Thanks for this tutorial, was very helpful for me. I also have a question about speed setting from 19:40. I don't get why we define speed here and why it has this value. Could you please explain me?
Because our ship is moving with some velocity so we define that
@@AnsysLearningPoint of course but we already defined inlet velocity for the fluid so the ship is moving in relation to the water, isnt it? Could you explain me where am I wrong? And why you put exacly 3.056? I'm sorry if my questions seems stupid for you but I'm just a begginer. Thanks for responding
@@pitachaja124pl yes you're right but this is not the case this case is that fluid move in opposite direction to ship like if ship is moving towards left then water move to right if we wouldn't put velocity of ship then it would be the case that ship is dragged by water towards right.
@@pitachaja124pl This could be interpreted as there is a current that is facing towards the ship (inlet condition) and the ship moves towards the current face-on (hull wall condition).
a trick: you can watch series at flixzone. I've been using it for watching all kinds of movies these days.
Thank you for thi useful tutorial. Can you make a tutorial for calculating wave resistance ?
If you recommend me a research ppr then I'd probably
@Ansys Learning Point There is a research paper called "CFD Simulations to Calculate the Resistance of A 17.500-DWT Tanker". If you share your email address, i can share some research papers with you. Thank you for your interest

Can you help me with a simulation in capturing the dynamic lift of the hull using dynamic meshing in ansys fluent? Simulation is almost ready, I am facing a error regarding negative cell volume. Pls, reply if u can help. thanks
It is a problem of fitting incorrect data
Brother I can't help you this rather I would suggest you that watch videos regarding dynamic meshing it has alot of data to be fitted in dynamic meshing tab which solve these problems. (Negative volume error) and I also suggest you to read the answer to queries of this problem by searching how to solve negative volume error in dynamic meshing
Hi man! I also would love to capture the dynamic lift on simulation. Were you able to finish this simulation? Could you help me somehow? Would be great if you share with me some tutorial or your settings
@@pitachaja124pl Yeah share your email address. I will send you some tutorials and suggestions when I get free. Thanks
@@meesamshah9291 I'm so happy to hear that :D my email:
mati-pie@tlen.pl
Can you share a journal that talks about this vidio? thanks mate
Plz find it yourself
