Boundary condition at infinity

Is there some way to set BC (of p and U) to some value very far from the object?
In this picture there are BC on cricle and very far away from it. There is no additional wall or someting.

I would suggest that you do some reading! There is no real concept within openFOAM of an infinite boundary condition. Rather you have to create a mesh such that the boundary is far (enough) away from your zone of interest to approximate infinite boundary conditions. At the 'freestream' boundaries you may impose a set of infinite conditions. Testing whether or not this boundary is far enough away to not influence results is important to validating your work.
For an example see $FOAM_TUTORIALS/incompressible/simpleFoam/airFoil2D
P.S. Many CFD textbooks and papers will cover this topic.
