How do I implement a symmetry boundary condition for a D2Q9 model
Hi,
If D2Q9 lattice like this;
e_0 =(0,0)
e_1=(1,0)*c
e_2=(0,1)*c
e_3=(-1,0)*c
e_4=(0,-1)*c
e_5=(1,1)*c
e_6=(-1,1)*c
e_7=(-1,-1)*c
e_8=(1,-1)*c
Symmetry BC:
f2=f4
f6=f7
f5=f6 (Yo must be careful incoming and outcoming direction)
It is a little bit confusing with regards to f5
Should f5 not be equal to f8?
Yes, you absoletly right. I had a mistake
