Hi sir, your video has cleared many doubts I had regarding mesh for CFD simulation in HM. But one thing I need clarification sir. If i had an assembly with 2 or 3 parts out of which one is solid (eg: Fluid-Solid Intersection problem) how to approach for meshing. How to extract fluid and solid volumes from the CAD file in HM and mesh them separately. How to account for interfaces between those 2 domains. Your suggestion will be greatly appreciated sir. Thank you
@@arsitech-ltd In your channel, I couldn't find any FSI videos sir. I found mostly abaqus videos only Can you please provide link or guide to those videos. Thank you.
Dear, May be due to different titles of videos you were unable to find. Named as water sloshing. ruclips.net/video/fsrzKhABYaw/видео.html ruclips.net/video/hwYxicVkvpk/видео.html ruclips.net/video/PJuqdi6TPAo/видео.html However, FSi problem also solved by Abaqus.
Dear, The unit is mm, hypermesh is unit less. During export mode you have to decide whether model is in mm or m. Layer thickness is not as per standard rule..just shown the example...how we can create inflation layers or boundary layer. Hypermesh provide calculator for 1st layer thickness calculation, one can calculate layer thickness by providing fluid properties, duct/chamber dimensions and flow characteristics.
Great video sir. Could you possibly make a video on homogenisation of fibre reinforced composites to evaluate their properties using ABAQUS and python scripting?
Good job, thanks! I have to study the airflow around an airplane, and I have to do the mesh in Hypermesh. The geometry is composed of a parallelepiped domain to which I made a Boolean operation to dig the airplane. I have successfully meshed the plane surface and domain walls, but I am unable to mesh the interior of the domain to create a tetra CFD mesh. How can I proceed concerning boundary selection, please?
@@arsitech-ltd Interior mesh for the domain, I already made boolean operation in the airplane. And I meshed all surfaces, but volume meshing for CFD failed...
Dear, Your problem statement (sentence) is not clear. How to apply for hex element - if you mean how to generate hex element then i would say for such geometry generating hex element throughout is not possible. If you are trying to prepare 2d model and importing in fluent then you need to follow different approach avilable on my channel. I suggest you to go through whole playlist - ruclips.net/p/PLdXwpuOm8L9puqMEWiecCPDhOcP-aiint
Hello sir, your videos are very informative. I want to model gabion wall and do the analysis in abaqus software. I've mailed you the description. I'll be Waiting for your reply. Thank you

Thank you so much, it was a great help
Dear,
Go through whole playlist of CFD mesh. You will get many interesting concepts.
Very very thank you for sharing your knowledge!!
It would be great if I get any content in CFD preprocessing for the Wing or Blade object.
Dear,
I suggest you to go through part 2 also for 2d mesh export.
@@arsitech-ltd Sure Sir. Thank you!!

Dear,
For fluid-structure interaction problems, I suggest you go with my FSi videos.
This video is purely for CFD pre-processing.

Sir, can you please clarify what is the unit followed for "First Layer Thickness" ? And, in general does Hypermesh use metres or mm for length?
Dear,
The unit is mm, hypermesh is unit less. During export mode you have to decide whether model is in mm or m.
Layer thickness is not as per standard rule..just shown the example...how we can create inflation layers or boundary layer.

@@arsitech-ltd Many thanks, Sir!
How to use Refinement box for Automobile cfd applications
Dear,
You need to just define the refinement box position.
Soon the video will be uploaded for the same. Stay tuned.
Great video sir. Could you possibly make a video on homogenisation of fibre reinforced composites to evaluate their properties using ABAQUS and python scripting?
Dear,
unfortunately I'm not expert in scripting.
Sir how do u generate both interface and wall elemets at one export cause I need to apply rotation and CHT in a problem.
Dear,
I not understood your question.
Please explain in detail.
If possible please make video on 6dof simulation in ansys.
Dear,
What do you mean by 6DOF simulation ?
Anyways, I'm not expert in ansys. I'm Abaqus and HyperWorks user.
@@arsitech-ltd OK sir

Dear,
What problem you are facing in interior meshing?
And of you are studying airflow around the plan (outside) only why you need interior mesh?
@@arsitech-ltd
Interior mesh for the domain, I already made boolean operation in the airplane. And I meshed all surfaces, but volume meshing for CFD failed...
Dear,
What error it shows?
@@arsitech-ltd
It shows: "element x=185 pairs error"
Perhaps it's mesh quality in element 185, but I don't know how to fix it...
In Hypermesh you are getting this Error?
As i know no such error code in Hypermesh.
You need to edit this element.
