Actually I realise that I don't include the centre point of the sphere, r=0 because it creates a singularity. Instead I start it at r=a, some finite value. So I'm not sure if I need to have symmetry...

I'm studying combustion where the zero-upstream velocity is a far-field velocity and there is a flame in the middle of the domain and the boundary condition at the outlet is a zero-gradient boundary...

Replies: 9 Boundary conditions using SIMPLER algorithm Views: 3,249 Posted By lost.identity Boundary conditions using SIMPLER algorithm I have seen a number of forum posts on this topic but I'm still struggling with my boundary conditions. I'm running a 1-D spherical calculation (only radial dependence considered). I decided to...
