Mesh in lumped elements

 

Hi everyone. 

I have been having trouble meshing lumped elements. When using adaptive meshing, the solver seems to refine the mesh indefinitely around the lumped element, which prevents me from reducing the convergence errors. I have also tried adjusting the radius parameter, but it does not seem to have any effect.

Could anyone recommend a proper way to mesh a lumped element or suggest which parameters I should adjust to avoid this issue?
