Combustion in a sphere

Caz

I am constructing a spherical vessel in which I will simulate combustion of methane and air (single phase). Ignition of the gas will be induced by raising the central spherical cell temperature to approx. 1100K.

So, my question is - can I use build where the north and south poles will cause possible problems for mesh analysis?

Do you know a way around these N & S poles occurring?

I am having major problems running meshbuild as it keeps crashing, and therefore prefer to use BUILD.
