ANSYS Fluent [CFD]: Making a Reduced Order Model [ROM] - (Start to Finish)
In this video, I show all the steps required to make a basic Reduced Order Model (ROM) in ANSYS 2023 R2.
The ROM is produced for a simplified room, with inlets, outlets, and a dividing partition.
The mesh is generated in Fluent Mesher, with default settings and a poly-hexcore mesh.
The solver settings are modified to increase simulation speed. However, this will result in reduced accuracy.
Finally, the results are displayed in a new Fluent session.

This video shows how to perform a simulation of a 2D lid-driven cavity with a large Reynolds number. This case is a key benchmark for CFD simulations, with data available for validation (to be covered in a future video). This analysis is performed in ANSYS Fluent (ANSYS 2024 R2), and covers the basics of: *Geometry creation in DesignModeler (shapes and dimensions) *Meshing and basic mesh contro...

Could you please share the case reference ? that interests me a lot.
I need too. It is impressive.
If anyone has suggestions for future topics or simulations you'd like to see covered, drop your ideas in the comments! It'd be awesome to explore more CFD concepts together.
Hello Dear, Can I have a full code, it can help to understand the interaction of two-phase flow Regards
Hi, Thanks for your comment. I plan to display the code for this in future videos. I will explain the theory and how I code it in the C programming language.
Amazing! I am also performing LBM based simulation for LDC for turbulence but I am not getting the desired results. May I know have you implemented the LES model to this simulation?
Thank you for your comment! No, I don't believe I did. I think I just used the MRT method, with many nodes. Which model are you using?
@@MechEngModelling Oh nice, I have plan for MRT but next year. Currently, I am using SRT based Fortran OpenACC code. So to the upper wall you applied force?
@@idreeskhan-zp5ey Excellent! Best of luck with the MRT model. For the upper wall, you add momentum to the diagonal lattice populations which are pointing back into the domain. For example (depending on how you number your lattice), my diagonal links, pointing into the domain are 7 and 8. I'm not familiar with fortran, but from my C code, all I do as modify the following on the top wall (after collision & bounceback): fn[x][y][7] -= moving_wall/6; fn[x][y][8] += moving_wall/6; Here, moving_wall is just my variable for the wall velocity. Hope that helps, but do let me know if you have any other questions
@@MechEngModelling Yes, exactly I did the same by adding (- and +) force, i.e., u0/6, to the upper wall along the x-axis. Currently, I am working on Forced Homogenous Isotropic Turbulence with DNS and LES. I am facing a kind of problem . while implementing the initial conditions and force in fourier space. If you have any public code, some suggestions/references would be great.
Can you please provide the code ?
Hi, Thanks for your comment. I plan to display the code for this in future videos. I will explain the theory and how I code it in the C programming language.
How is the velocity in Re decided?
it is sqrt(Wg). W is the width of the domain, and g is gravity.
I know the guy, proper brainbox
