I think eddy3d is a great plug-in for outdoor ventilation analysis. Now I need do some validation before outdoor wind analysis by Eddy3d. I found the validation file in Eddy3d is based on Jiang’s paper.
As far as my opinion，the Jiang’s paper is good for outdoor and indoor wind ventilation validation，but not for the outdoor wind analysis which related with the building blocks.
The research always use the “AIJ guidelines for practical applications of CFD” to do outdoor wind validation.I want use eddy3d to do the validation. But I have some questions about it. Maybe someone can help，THX for anyone who pay attention to my questions.
In Eddy3D we can set gradient wind，but we can only set one Z reference and U reference. In “AIJ guidelines” it gives me the list of Z reference and U reference. So which Z reference should I choose？Or do you know how to solve this problem？
In Eddy3D，the plug-in let me define block size and the cell size，does the cell size means the cell on the building surface？The result is 4 now， the 4 means 4 times or 4 levels？
The Eddy3D need define the accuracy of the mesh， so what is the meaning of the “ACCbuilding” and other “ACC-XXXX”？
If I set 4，is it means 4 level cell or the cell size is 4？
In Eddy3D， the plug-in can define Relaxation factors， the default setting is Fluent， so What is the different between Fluent and OpenFOAM setting？
There is “Solution and Algorithm control”，but the example did not set this， do I need set something or just let it be default？
5. I always used Fluent to do the CFD simulation. In Fluent，if I set 1000 iteration and maybe before 1000 the result is convergence， the simulation will stop. But I think Eddy3D will not stop before iteration setting. Do anyone have any suggestion about this part？
THX for anyone who can help me and I will keep in this validation simulation and I will upload my file when the questions have been solved~~~
PS ： the attachment files are “AIJ guidelines” validation case. And after I did this validation I will upload the data. THX~~~~
