Hi there, a very basic question in the creating STL file section: could you please let me know why you are creating the mesh in 22:57? Why not export Fuse_2_1 directly as a STL file? apologies for the possibly stupid question. And thank you for the useful videos that you've put up on your channel!
It's not a stupid question. It's a very good question leading to a very important thing you need to be careful about. When you directly export the fused solid as an STL, the triangles are very coarse which is not very good for snappyHexMesh. That's why I generated mesh to create a fine STL.
@@vivekfrancis139 It's my pleasure to explain this very important detail. For more insights to OpenFOAM, I have launched my blog cfdmonkey.com where I write about a lot of OpenFOAM related materials
Short answer: yes. Long answer: you need to compute many cases if you want to cover the frequency range of your interest. It is computationally expensive. Conclusion: it is better to use OpenFOAM to compute RAOs for regions with high non linearities like large wave steepness.

@@thawtar682 Thank you for the prompt response. I think I understand your point well now. And please continue with the good work that you are doing! 🙂

@@thawtar682 Thank you♥
Can you upload the PPt u use for it? please
What is the 3D modelling software that u used? I think u said it, but the audio quality is quite bad. Is the software free?
I used Salome for creating the 3D model.
I am sorry that the audio was bad. Sorry for your bad experience
Can we use OpenFoam to generate RAO's?
Short answer: yes.

@@thawtar682 Are you planning for a tutorial on the generation of RAO's in OpenFoam?
@@apishdad that's the main purpose of this series
iam waiting for part 2
Thank you for your interest! Coming soon. Everything is working well. I am just a bit busy to record the video.
