Using Adaptmesh

Hello everyone,
I’m facing an issue with using Adaptmesh on this type of mesh, it’s not functioning as expected. Could anyone advise me on which parameters of adaptmesh might help resolve this problem?
Thank you in advance for your assistance!

Th problem for mesh adaptation is very difficult due of 2 big circle very very close and with a coarse mesh. so please refine the mesh on this 2 circle.

I am seeking guidance on whether the mesh can be refined automatically using adaptmesh, rather than manually. Additionally, when initiating with a large mesh, adaptmesh still results in a crash. Could you please advise if there are specific parameters within adaptmesh that could address this issue?
