How circular microchannel roughness geometry and meshing can be done??

Shuveksha · May 21, 2021, 10:10

I am looking towards simulation of circular microchannel and i created the geometry and mesh in micrometeres. Now in Fluent solver, micrometers units is not there and now will i have to put scaling factors and then scale or if mesh and geometry are already in microcmeters,Fluent directly keeps the domain extents in 10^-6. So what should i do? If already in domain extents by keeping the units metre, its already in value of 10^-6, do i need to scale again or leave and continue?
It is also showing solution is converged? Is it sue to the small dimension? Please give me idea.

Run the mesh check and you can check the domain extents.
