Please suggest best Mesh Partitioning methods (Fluent) for very small grids used in Micro-combustion in 2D tubes?

My simulation crashes frequently when I use very small grids ( less than 0.05 mm). It doesn't for grids > 0.1 mm. Always there is an error related to partitioning. When I decrease the number...
