periodic bc

I am modelling a flow inside a sphere. Is it possible to model 1/4 th sector of sphere with periodc bounary condition.

come on somebody hel me with this case

it depends on your BC.
If they are periodic, you can use periodic BC
If they are periodic, you can use symmetric BC (or 2d-axi model)

Thanks for the help.

I am modelling spherical flame propagation inside a sphere. Please let me know now.

I don't think flame propagation is periodic / symmetric.
But I am not expert
If I am right, then you will have to compute the full sphere.
