[New-to-CFD]

Hi Everyone,

Extremely basic questions, any help would be appreciated!!

I am very new to CFD and Openfoam. I am doing my masters thesis on concrete armour units on breakwaters, and would like to build a simulation to model a typical section of sloping beach with a layer of concrete armour units on an impermeable breakwater structure.

1. What is the best solver to use for this application?
2.How can I model the beach with a given SWL with regular oscillating waves at the inlet?
3. most importantly how can I model the individual armour units themselves (can jsut be cubes for now to keep it simple)? Is it possible to measure contact point stresses on the impermeable base and internal stresses in individual units?
4. What is the easiest way to import geometry from Autocad?

PLEASE HELP!!

Much appreciated

Hi there,

1. I have worked on that before, see the attachment and check olaFoam out:

https://sites.google.com/site/olafoamcfd/

2. OlaFoam provides tutorials that can help you setting up your case. Check the wiki site

https://openfoamwiki.net/index.php/Contrib/OLAFOAM

3. At this stage OpenFOAM cannot handle fluids and mechanics at the same time. Last year I was working in a coupled tool with FEM-DEM software for that purpose. You can find some information here:

4. Just export your solid' surfaces as STL or OBJ.

Best,

Pablo

Hi Pablo,

Thanks very much I will look into this! Was the attachment you provided produced on olaFoam? How did you model the individual units from what I see the breakwater tutorial only has a porosity factor for the wall?

Yes, the picture attached has been performed with olaFoam.

The underlayer is a porous medium, the units are obstacles and have been meshed around.

Thank you very much for your help! I will be looking into this in the next week or so and will likely come back with more questions.

Could you explain any further how to import a mesh geometry once saved as an STL file? How do I put this into the geometry source code and how will I easily able to define properties without having to deal with the point numbers/faces etc.?

I am planning to model a simple breakwater with just cubes to start, how could i import this and make all the cubes wall conditions?

or please advise!! i really appreciate it i am very new
