(60fps) Getting started: Ship resistance using VOF in Ansys Fluent

Basic introductory Computational Fluid Dynamics (CFD) simulation tutorial using Ansys
1. Creating a simple 3D CAD barge model in Ansys SpaceClaim
2. Generating a 3D unstructured mesh using the Fluent Watertight Geometry Workflow with body of influence
3. Setting up a Volume of Fluid (VOF) Multiphase Model (air and water) with Open Channel Flow Sub-Model in Ansys Fluent solver
4. Solving and post-processing, plotting free surface height using isosurface, calculating drag value

Thanks mate, just what I am looking for

[@jlaclee]

Thanks for posting a good tutorial.

[@AsifRaza-jt5go]

very good tutorial

[@mehmetdelikan4687]

Thank you for this useful tutorial. Can you make a tutorial for calculating wave resistance ?

[@meesamshah9291]

very nice video. Can you make same tutorial for dynamic meshing for capturing the sinkage and trim of boat? Thanks

[@muhammadmosaad4556]

Thanks to the most

[@khangvo5112]

nice video tks sir

[@antonshevelev5034]

What about dynamic mesh in your’s case?)

[@afiqwafiy6980]

i want to ask there is specific size for the domain to find ship resistance or you just create the domain according your size of vessel??i already read many paper but i still dont get the answer..if you dont mind can you help me give the answer

[@yaofu4883]

im not sure if i fully understand what you want. do you want the fluent to report the ship resistance？ if so, you can go to the "report definition" , which is in the "solution" option, in oder to predefine the drag force before the calculation. Then you will get the resistance reported. Or you can go to the CFD result to calculate the resistance on the ship hull.

[@aldiasbahatmaka1052]

you can check the domain size through this link: ittc.info/media/1357/75-03-02-03.pdf
ITTC's recommendation.

Hey. Thank you so much for this video. I keep getting this error. "Cannot calculate force. variable 'mixture.volume fraction' does not exist"
Could you please help me to fix this?

[@tumulpurwar8812]

Have you choosed vof?

[@chrishmalperera]

@@tumulpurwar8812 yes I have

useless, no sound no insight, just superficial, conveying knowledge should use a refined scientific language, this doesn't solve the multiphase equations but rolls back to stone age or further back in prehistoric age where human language had not yet developed. Should be flagged as misleading
