In this session, join KETIV Application Engineer, Snigdha Sarkar as she goes over the guided meshing workflow for Watertight Geometry with clean CAD in Ansys Fluent Meshing. This session follows the easy and intuitive steps in the guided workflow to auto-generate a high quality CFD mesh in Fluent meshing. Some of the important steps that are covered include:
-Introduction to the watertight geometry workflow GUI and features
-Surface meshing using guided workflow
-Volume meshing using guided workflow
This session is highly recommended for CFD analysts who are looking to reduce their simulation pre-processing time, and simplify their CFD workflow by taking advantage of Fluent’s single window workflow from geometry import to meshing, solving and post-processing.

Thanks Snigdha. It was a very nice learning.

Hi! Very helpful tutorial! I wanted to know more about how to improve the mesh in terms of skewness and orthogonality. Hopefully you could provide a tutorial on this as well, thanks!

Additionally, if I use poly-hexcore as in the video, how do I know if the orthogonality of my mesh is good? What value should I aim for?

@hamzaseker8324 2 жыл бұрын

hi, thats great job. is it appropriate to use dynamic mech with poly-hexcore mesh ?

it was a paper of Roach, for mesh Independence study. one may use also richardson's extrapolation method

Hi. Question. Should the body of influence be a separate part? I'm using designmodeler and not spaceclaim, but i don't think that makes a difference right? Reason is, I tried to form a new part, but it couldnt identify the boi. Thanks!

hi very good video I just want to ask in case there is an interface what should I do to identify it

Hello, question here on capping. I want to import cad files from autodesk inventor. How can i seal inlet and outlet when i dont have it already prepared? In autodesk CFD mesh creation started at the end, after all other settings, including materials and internal volume definition, so there you were still working with CAD edges and not triangular mesh.

Say you make a mutlibody part in Design Modeler, you arive to Fluent, and you'd like to setup boundary conditions, in the BC tab. There will be listed several entities, each belonging to a separate body of a multibody part, that belong to a same boundary named selection (face), say outlet. Is there a way to merge them and prescribe the boundary condition over the whole face rather than separately? Thanks

At 43:01 the minimum quality is 0.11, how can we refine that! Also for next videos if you go through skewness and orthogonal quality individually, we can see how good the mesh quality is and how it can be improved. Secondly, by looking at polyhedral mesh we can see compromise at the orthogonality, so, are there limitations to application of some turbulence models because of low orthogonality? Thanks and keep up the good work!

We will cover mesh refinement and compliance with mesh quality in a future AVA. The purpose of this AVA was to highlight the ease of use of this task-based workflow, hence mesh quality wasn't prioritized. Thank you for the feedback! Snigdha Sarkar | KETIV | Applications Engineer

I am using fluent 18 and there is No workflow window when opening fluent meshing is it not available in fluent 18 version or is there anything i should do to enable it from my side

Great tutorial. One quick question: what is the advantage of using poly-hexcore mesh compared to all poly mesh? Thanks.

@johndao8592 3 жыл бұрын

Hello Ran, Our Ansys partners answer this question best. Please take a look here: www.ansys.com/products/fluids/ansys-fluent/mosaic-meshing-technology "Generate Mosaic-enabled Poly-Hexcore meshes up to 10x faster using parallel processing. The patent-pending Mosaic algorithm creates adaptive conformal mesh interfaces for the best combination of speed and accuracy. No need to buy a separate HPC license. The following example shows a comparison between Poly-Hexcore with Mosaic technology and conventional all-polyhedral meshing technology with a bluff body flame holder. The Mosaic mesh had fewer, better quality cells, requiring one-third less memory, and delivered a solution two-times faster with higher accuracy." Sincerely, JD, from KETIV

Can you please include tutorials on how to mesh rotating fluid domain such as Horizontal axis wind turbine? I believe this kind of meshing involves at least 2 different fluid domains..

@xuxu119 2 жыл бұрын

I was also looking for this workflow on youtube but as far as i know the watertight geometry workflow only allows for 1 domain, meaning the interface layer for the MRF between rotating and stationary part cant be created. In the fluent solver you can however split the zones/wall to create an interface but I havent had any luck with that either and i think the shared topology erased all the interface lines. I am looking forward to someone showing me a working MRF under the watertight workflow.

How do I create zones on stl of my geometry? I am not able to understand how I can create inlet and outlet

@fritzchennummber1 3 жыл бұрын

kzfaq.info/get/bejne/aMmpqseBx9W8qas.html here you can see a workflow for opensource cfd with OpenFOAM, there it is mentioned how to create inlet and outlet for STL. If you are interested in creating Inlet and Outlet for a STL in SpaceClaim, then look for the Groups Setting by the modell tree. Hope this helps

@@KETIVTechnologies Looking forward to this. I thought the watertight geometry workflow only allows a single domain so MRF rotating studies cant be done under the watertight geometry workflow. Is this true?
