Hi OpenFOAM users! I found that using the actuationDiskSource there is a small jump in the velocity field near the actuator disc cells. I couldnt found a solution on internet. Any help?

This is not a bug.

If you want a clean jump, use face jump conditions such as fan instead of cell zone body force
