Greetings, colleagues!

I need to refine mesh along some trace. For example, I have a set of points, and I need to refine mesh along the line connecting these points. Please, help me, how to do this.

To explain why I need it. I calculate the chemical reactions and mass transfer on a stationary velocity field (obtained previously from simpleFoam). The case is the flow around an obstacle. And I need to refine mesh along the separatrix which divides the recirculation zone and the core of flow. I can estimate this separatrix from ParaView (e.g. obtain some points and interpolate between them).

As I understand, I need to define some cellSet and then refine it. But how can I define the cellSet in right manner, i.e. along the
separatrix curve?

Please, help.

Best regards, Aleksey.
