Question:
For the nonlinear adpative region, you need a body with enough bulk volume. Thin bodies may not allow enough room to refine the mesh. Your model looks to have thin bodies. Have it remesh early and often, before the body gets too deformed, or else it may not remesh with an acceptable quality. The purpose of nonlinear adaptive region is to repair a distorted mesh in order to overcome convergence problems caused by the distortion. It is effective only when the mesh distortion is caused by a large, nonuniform deformation. Nonlinear adaptive region cannot help if divergence occurs for any other reason such as unstable material, unstable structures, or numerical instabilities.
Check to see if your hyperelastic material properties are a cause of the problem. Choose a simpler material model to see if convergence is easy and the model behaves correctly. You could try the neoprene rubber material from the hyperelastic materials library.
Answer: Silicone rubber have high bulk modulus and as i am using non linear adaptive meshing only for Rubber, so i think this should not be a problem.
As earlier when i was not using non linear adaption mesh for rubber, i was ever getting, elements in "identify element violations",so thus got tired and switched to "nonlinear adpative region" for rubber.
I have checked cvomplete door aseembly when i assumed rubber as steel,it had no problem in simulation, but as soon as i convert to rubber or can say hyperelastic material, it ever run, and never converge completely, even for simplified model of real assembly its not converging(which hardly contain 2 structural items, one is rubber other is door.
