Varying mesh size
 

Hello REEF3D Team,
I am trying to define different mesh sizes for the different zone in the x direction but I am confused about the parameters mentioned in the DiveMesh Module.
In B 121 what do N1 and X1 Signify? As shown in the image I attached should it be like ?

B 101 8
B 121 150 15 200 25 150

Thank you

Hey

N1, N2, N3 are the number of cells inside the given space -> cell size x1 = length/N1. x1 and x2 are the coordinate of where the respective zone ends/ another one starts -> for your application x1 = 15, x2 = 25

Also, maybe try out B101 11 as the transitions between cell sizes are smoother, and I find that such an application is more stable. For B 127 your input would be B 127 0.05 0.1 20 10 1.1 (<- maybe play with the stretching r)

Cheers

Thanks for the reply,

I tried same for B 101 5 as you mentioned but it is showing error, it seems like i am missing something
