Boundary condition
 

I am conducting a 3D simulation for the drag coefficient of a cylinder.

The flow is along the x-axis, and I am using a 2D rectangular(x-y) domain with a circular mesh that is pulled in the z-axis direction.

For the z-axis boundaries, I am applying periodic conditions, and there are options for both non-conformal periodic interface and conformal periodic interface.

I am currently using the non-conformal periodic interface, and I am curious whether this configuration is appropriate for the simulation.

Could you provide information on both types of interface conditions?

Thank you :D
