how to active adaptive mesh option in ADINA System?

hello to every body ;)

  Iam hasani- gradute student

I'm new user in adina. i worked by ansys and abaqus for several projects.

in adina  when i choose control>solution process...>adaptive meshing> full the program return it to none!.

i tried to understand about the reason. but in fact i can not find the problem.

i think in program , there are some constraints that should be change before the full adaptive meshing.

please help to find the problem. thanks
