Jacobian error for 3D geometry

I tried to solve a 3D geometry in RF Physics, consisting of two cylinders (fiber - core and clad) and a removing part on top (ablation) and two stack layers on the top.
Depending on the geometry building steps, I have different errors in the results...
first geometry building steps: two concentric cilinders, a block
union operation for cilinders
substraction for the union and block
two blocks
union
at least this gives no building errors in geometry. But at the frequency analysis, there is a Jacobian error.
Does this errors offen appears due to the
a. step (mesh building) - but I build the mesh on particular for each domain
b. initial conditions
c. when the difference of the layers width are too hight (for instance 40nm and 120um) ?
Best regards.
