ABAQUS STRESS-DISPLACEMENT CONTROL

[Mirelala]

I am working at the example 3.1.1 (Tire) trying to know the stresses in a point not declared by the original input. I am not able to do this and I have difficulty in order to  write the command line.
Besides I would like to see the vertical stress instead of Von Mises stress.

The second problem is related with the displacement control.I tried just to change the value of the displacement but now the program says that there is a mistake.

Thanks for the help
