Dear Daniel

The code solve a solid mechanic model with a plastic material model. The 
WorkStream is used for matrix and residual assembly (like step-44). So I 
just add some new classes  (PerTaskData and ScratchData) and the most parts 
of the code is not changed. The code works similar to the its serial 
version without any problem when the local adaptive refinement is not 
active. During a load increment, let the solution to time step Tn be given. 
The full problem is solved. First, I refine the mesh based on the new 
solution and interpolate the old solution (at Tn ) onto the new mesh. Then 
I solve for the solution at Tn+1 again, but on the refined mesh. This 
process is tested in the previous version of the code. However, in the new 
code after the first refinement, the solution for Tn+ has a constant 
residual error during Newton iteration. 

Thank you
P.
