Hi team REEF3ED
I want to ask you if you have some tutorial about how to implement nets in floating bodies (simulating aquaculture strctures, like some publications that use the software). I have tried with the comands availables in the guide (since X320 to X324) but I have some problems. Fir example when I want to simulate a box with statics nets walls, this don't move with the solid. Maybe I have to execute other comand.

Thank you very much
Pablo

I want to simulate a free decay test of a generic structure to know how the software works with the implementation of nets. My idea is to implement rectangular nets on the side of the platform, but I have some problems with the input data in "ctrl.txt" file.
Atached to the post is an image of the solid that I create for that exercise. By the moment I was trying to use statics net walls for that, but its don't move withthe floading body.
I don't know if I making a mistake choosing that option, or I have to do something else, or choose another configuration.

Thanks
Pablo

Hi Pablo,

Good to know you're working on the net implementation using R3D. As you know, X 320 is coded to specify the net type in quasi-static or dynamic solutions. But, if you talk about the net with a floating/solid body, the only way is to refer to net_sheet_ini.cpp file or revise the code as you want.

Cheers,
Gang

Hi Pablo,

Could you please show your revised "net_sheet_ini.cpp" to us? As well as the control and ctrl files?

Regards,
Gang

Hi team REEF3D!
The following is an example codes of my "control.txt" and "ctr.txt" files. As I wrote, by the moment I was trying to simulate a simley decay test with the platform that I show you.
I still don't know how to work with the "net_sheet_ini.cpp" file or call it. Do you have any example of how to work with it.
I'm interested in implement that kind of simulation (floading structure + nets) in my master degree tesis.

Thank you very much!

Hi team REEF3D
I have lookinf fot the "net_sheet_ini.cpp" file into the "src" folder of REEF3D into the repository on Github, but I can not find anithing related there. I'm wrong looking for there? And if i find that, How can I work it?
I'm really exited to learn about that. I hope your answer.

Regards
Pablo

Update:

Finally i found the "net_sheet_ini.cpp" into the "src" folder of the REEF3D folder in the "cp /mnt/c/Users/<windows username>/Downloads/<ParaviewLinuxArchiveName>" location.
So, now I need to know how to call this script for try an example of this kind of simulation. By the moment I want to simulate one of the examples (Havfamr 2, DeppBlue 1 or other).
How can I do that? I just need a little help getting started.

Regards
Pablo

Update:
I was reading the "net_sheet_ini.cpp" file, and finally understanding it.
So the only thing that I need is know how to execute the file.

Hi Pablo,

Using X 320 4 and X 321, X 322, your revised net_sheet_ini.cpp can be execuated.

Cheers,
Gang

Thank you very much!
I'm going to work with that information.

Hi again team REEF3D!

I have read the "net_sheet_ini.cpp" file, and I have some questions about the discretization of the net using the screen force model.
Taking as example the "OceanFarm 1" structure (available as aexample in the file), it shows three kinds of nets, the main cylinder, the bottom cone and the bulkheads. For everyone, it is calculated the number of triangles for the discretization (variable "tend" in "NSI_1.PNG" image). My question is related to the obtention of this number for every net. I mean, for the cylinder is related to the discretization asigned in the "ctrl.txt" file (in X321, with "nd" and "nl"), but in the case of the bulkheads only considere 2 triangles for each one (6 in total due to the 3 bulkhead in total). In the case that I present previously in this post (only considering rectangular nets on the sides) I'm little confused about how to set the discretization of the sheets.
Have I to considere only 2 triangles for every wall? Or Have I to discretize with a bigger number of elements? and, How I determine this number of elements?

Thank you very much
Regards
Pablo

Hi again
I edited the "net_sheet_ini.cpp" file (attached to this comment), and implement a new structure (image attached as"Structure.PNG") instead of the first that I shown. I want to implement a mooving sheet in the front face of that structure (as is writted in the "net_sheet_ini.cpp" file), but REEF don't recognize the changes and and it throws error (like is shown in the two pictures of the ubuntu window). The sheets that generate the commands ("Net_Sheet.PNG") are from "Ocean Farm 1", and I don't know why it'a happening.
The only thing that I did for this case was replace the "net_sheet_ini.cpp" file of the "src" folder of the REEF3D folder in the "cp /mnt/c/Users" location.

is it enough with that? What I'm doing wrong? How can I proceed for call the "net_sheet_ini.cpp" file that I create?

Please don't forget to answer the previous question in that post.

Thank yo very much
Regards
Pablo
